Prevalence of Diarylprolinol Silyl Ethers as Catalysts in Total Synthesis and Patents

Diarylprolinol silyl ethers are among the most utilized stereoselective organocatalysts for the construction of complex molecules. With their debut in 2005, these catalysts have been applied in numerous method developments primarily leveraging enamine and iminium-ion catalysis. These strategies have extended into the preparation of complex molecules in both academic and industrial settings. This Review intends to give an overview of the application of the diarylprolinol silyl ether catalysts in total synthesis. Furthermore, integration of these catalysts in patent literature is also disclosed highlighting the versatility of the catalytic system.

Structure-activity relationship of biakamide, selective growth inhibitors under nutrient-starved condition from marine sponge

The tumor microenvironment is considered as one of the important targets for anticancer drug discovery. In particular, nutrient deficiency may be observed in tumor microenvironment; biakamides A-D (1-4) isolated from marine sponge Petrosaspongia sp. as growth inhibitors against cancer cells adapted to glucose-deprived conditions have potential as new drugs and tools for elucidating adaptation mechanisms to these conditions. In this paper, we investigated structure-activity relationship (SAR) of biakamide to create easily accessible analog and gain insights about participation of the substructures to growth-inhibitory activity toward development of anticancer drug. This work revealed that 14,15-dinor-biakamide C (5), which is easily accessible, has similar activity to natural biakamide C (3). In addition, detailed SAR study showed the terminal acyl chain is important for interacting with target molecule and amide part including thiazole ring has acceptability to convert structures without losing activity.

Synthesis of the ABCDEFG ring system of maitotoxin

Maitotoxin (1) continues to fascinate scientists not only because of its size and potent neurotoxicity but also due to its molecular architecture. To provide further support for its structure and facilitate fragment-based biological studies, we developed an efficient chemical synthesis of the ABCDEFG segment 3 of maitotoxin. 13C NMR chemical shift comparisons of synthetic 3 with the corresponding values for the same carbons of maitotoxin revealed a close match, providing compelling evidence for the correctness of the originally assigned structure to this polycyclic system of the natural product. The synthetic strategy for the synthesis of 3 relied heavily on our previously developed furan-based technology involving sequential Noyori asymmetric reduction and Achmatowicz rearrangement for the construction of the required tetrahydropyran building blocks, and employed a B-alkyl Suzuki coupling and a Horner-Wadsworth-Emmons olefination to accomplish their assembly and elaboration to the final target molecule.

Potent HIV-1 protease inhibitors incorporating squaramide-derived P2 ligands: Design, synthesis, and biological evaluation

We describe the design, synthesis, and biological evaluation of novel HIV-1 protease inhibitors containing a squaramide-derived scaffold as the P2 ligand in combination with a (R)-hydroxyethylamine sulfonamide isostere. Inhibitor 3h with an N-methyl-3-(R)-aminotetrahydrofuranyl squaramide P2-ligand displayed an HIV-1 protease inhibitory Ki value of 0.51 nM. An energy minimized model of 3h revealed the major molecular interactions between HIV-1 protease active site and the tetrahydrofuranyl squaramide scaffold that may be responsible for its potent activity.
