Tandem cross metathesis and intramolecular aza-Michael reaction to synthesize bicyclic piperidines and indolizidine 167E

We have successfully transformed the terminal alkenes of dihydropyridones to the alpha,beta-unsaturated esters by cross metathesis (CM). After detosylation the secondary amides can undergo the intramolecular aza-Michael reaction to give the bicyclic piperidine structures. The stereoselectivity of the aza-Michael reaction is determined by the size of the newly formed ring. With simple transformations we have also achieved the synthesis of indolizidine 167E. 2012 Elsevier Ltd. All rights reserved.

1,2,3-Triazole based bisphosphine, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)-phenyl)-4-phenyl-1: H -1,2,3-triazole: An ambidentate ligand with switchable coordination modes

The reaction of 1-(2-bromophenyl)-4-phenyl-1H-1,2,3-triazole (1) with Ph2PCl yielded bisphosphine, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)phenyl)-4-phenyl-1H-1,2,3-triazole (2). Bisphosphine 2 exhibits ambidentate character in either the kappa2-P,N or kappa2-P,P coordination mode. Treatment of 2 with [M(CO)4(piperidine)2] (M = Mo and W) yielded kappa2-P,N and kappa2-P,P coordinated Mo0 and W0 complexes [M(CO)4(2)] [M = W-kappa2-P,N (4); Mo-kappa2-P,P (5); W-kappa2-P,P (6)] depending on the reaction conditions. Formation and stability of kappa2-P,P coordinated Mo0 and W0 complexes were assessed by time dependent 31P{1H} NMR experiments and DFT studies. The complex 4 on treatment with [AuCl(SMe2)] afforded the hetero-bimetallic complex [mu-PN,P-{o-Ph2P(C6H4){1,2,3-N3C(Ph)C(PPh2AuCl)}-kappa2-P,N}W(CO)4] (7). The 1:1 reaction between 2 and [CpRu(PPh3)2Cl] yielded [(eta5-C5H5)RuCl{o-Ph2P(C6H4){1,2,3-N3C(Ph)C(PPh2)}}-kappa2-P,P] (8), whereas the similar reaction with [Ru(eta6-p-cymene)Cl2]2 in a 2:1 molar ratio produced a cationic complex [(eta6-p-cymene)RuCl{o-Ph2P(C6H4){1,2,3-N3C(Ph)C(PPh2)}}-kappa2-P,N]Cl (9). Similarly, treatment of 2 with [M(COD)(Cl)2] (M = Pd and Pt) in a 1:1 molar ratio yielded PdII and PtII complexes [{o-Ph2P(C6H4){1,2,3-N3C(Ph)C(PPh2)}-kappa2-P,P}PdCl2] (10) and [{o-Ph2P(C6H4){1,2,3-N3C(Ph)C(PPh2)}-kappa2-P,P}PtCl2] (11). The reaction of 2 with 2 equiv. of [AuCl(SMe2)] afforded [Au2Cl2{o-Ph2P(C6H4){1,2,3-N3C(Ph)C(PPh2)}}-mu-P,P] (12). Most of the complexes have been structurally characterized. Palladium complex 10 shows excellent catalytic activity towards Cu-free Sonogashira alkynylation/cyclization reactions.

delta-Acidity of benzene in [(benzene)RuII(N-N)Cl]+. Crystal structures, nuclear magnetic resonance spectra and nucleus independent chemical shifts

The ligands L1 and L2 are 1:1 condensates of acetylacetone and 2-hydrazinopyridine and 2-hydrazinobenzothiazole respectively. Reactions of these ligands with [RuCl2(C6H6)]2 in 2:1 M proportions in the presence of excess NH4PF6 yield two complexes ? dark red [(C6H6)Ru(L1)Cl]PF6 (1) and yellow [(C6H6)Ru(L2)Cl]PF6 (2). Their X-ray crystal structures have been determined. They are 1:1 electrolytes in dimethylsulfoxide (dmso). The bonding in the complexes involves significant back donation from the filled dxy orbital of the metal to the empty pi? orbital of coordinated benzene, as confirmed by the visualization of the HOMOs in 1 and 2 obtained from the density functional theory (DFT) calculations. As a consequence, in the 1H NMR spectra in dmso-d6 the benzene protons are shifted to lower values of 6.23 (in 1) and 6.37 (in 2) from 7.26 ppm of the free benzene. Thus the protons of the ligated benzene become less deshielded compared to free benzene. Further a concomitant lengthening of the C?C bonds in the coordinated benzene by ?0.04 A is observed. A pseudo-octahedral geometry of Ru(II) in 1 and 2 is stipulated from a d-d transition which gives the 10 Dq value of 24,500 in 1 and 24,000 cm?1 in 2. The NICS(0) value, an index of aromaticity, calculated at the center of the benzene ring by GIAO method at BP86/LanL2DZ level, of ?6.53 ppm in free benzene becomes more negative in 1 (?20.36 ppm) and 2 (?21.45 ppm). Thus coordinated benzene becomes more aromatic from the point of view of NICS. In addition when NICS is varied as a function of the distance (up to 0.8 A) above the center of the benzene ring, it increases in complexes 1 and 2 whereas in unbound benzene it decreases.

Rapid two-step synthesis of drug-like polycyclic substances by sequential multi-catalysis cascade reactions

An efficient amino acid-/self-/base-/ruthenium-/thermal-catalyzed two-step process for the synthesis of functionalized drug-like carbocycles was achieved through combinations of cascade TCRA/C-allylation/enyne-RCM/Diels-Alder reactions as key steps starting from simple acyclic substrates. In this communication, we report the two-step synthesis of drug-like carbocycles through a combination of organocatalysis with ruthenium-catalysis.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 246047-72-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 246047-72-3, in my other articles.

Diversity-oriented synthesis of 17-spirosteroids

A diversity-oriented synthesis (DOS) approach has been used to functionalize 17-ethynyl-17-hydroxysteroids through a one-pot procedure involving a ring-closing enyne metathesis (RCEYM) and a Diels?Alder reaction on the resulting diene, under microwave irradiations. Taking advantage of the propargyl alcohol moiety present on commercially available steroids, this classical strategy was applied to mestranol and lynestrenol, giving a collection of new complex 17-spirosteroids.

Concentrated solar radiation aided energy efficient protocol for oxidation of alcohol using biodegradable task specific ionic liquid-choline peroxydisulfate

An eco-friendly and energy efficient protocol for selective oxidation of alcohols to aldehydes/ketones has been developed by using Choline Peroxydisulfate under concentrated solar radiation (CSR). Choline and peroxydisulfate based biodegradable oxidizing task specific ionic liquid (TSIL) ChPS was synthesized, characterized, and evaluated. The oxidizing property shows excellent performance as an effective oxidant. Comparative energy calculations between conventional and CSR method show, CSR method is superior alternative pathway with high energy conservation method (?90%). Incorporation of biodegradable ionic liquid and renewable energy source, makes the present protocol environmentally benign and energy efficient.

A facile domino metathetic route to a thapsigargin skeleton

A facile synthesis of a 5,7,5-fused ring system that is present in thapsigargins belonging to a novel family of sequiterpene lactones, guainanolides, using domino enyne – RCM was studied. The synthesis began with the readily available ketone. Addition of allenyl Grignard reagent at low temperature afforded the tertiary alcohol in good yield. Selective removal of the more exposed acetonide group followed by cleavage of the diol with silica gel supported NaIO4 provided the first key intermediate aldehyde in high yield. The stereochemistry of the Grignard reaction was tentatively assigned in a scheme based on the Felkin-Anh model.
