The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2-Chloro-6-nitrobenzo[d]thiazole(SMILESS: O=[N+](C1=CC=C2N=C(Cl)SC2=C1)[O-],cas:2407-11-6) is researched.Application In Synthesis of Dirhodium(II) tetrakis(caprolactam). The article 《Stereodivergent, Diels-Alder-initiated organocascades employing α,β-unsaturated acylammonium salts: scope, mechanism, and application》 in relation to this compound, is published in Chemical Science. Let’s take a look at the latest research on this compound (cas:2407-11-6).
Chiral α,β-unsaturated acylammonium salts are novel dienophiles enabling enantioselective Diels-Alder-lactonization (DAL) organocascades leading to cis- and trans-fused, bicyclic γ- and δ-lactones from readily prepared dienes, commodity acid chlorides, and a chiral isothiourea organocatalyst under mild conditions. The authors describe extensions of stereodivergent DAL organocascades to other racemic dienes bearing pendant secondary and tertiary alcs., and application to a formal synthesis of (+)-dihydrocompactin is described. A combined exptl. and computational study of unsaturated acylammonium salt formation and the entire DAL organocascade pathway provide a rationalization of the effect of Bronsted base additives and enabled a controllable, diastereodivergent DAL process leading to a full complement of possible stereoisomeric products. Evaluation of free energy and enthalpy barriers in conjunction with exptl. observed temperature effects revealed that the DAL is a rare case of an entropy-controlled diastereoselective process. NMR anal. of diene alc.-Bronsted base interactions and computational studies provide a plausible explanation of observed stabilization of exo transition-state structures through H-bonding effects.
As far as I know, this compound(2407-11-6)Application In Synthesis of 2-Chloro-6-nitrobenzo[d]thiazole can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
