Prolinamide bridged silsesquioxane as an efficient, eco-compatible and recyclable chiral organocatalyst

A new organic-inorganic hybrid silica material derived from a bis-silylated prolinamide by sol-gel methodology has been successfully applied as a supported organocatalyst in asymmetric aldol and Michael reactions. Our immobilized system presents similar performances to homogeneous prolinamides and added advantages of easy recovery and good recyclability. It fits green chemistry requirements as the reactions are performed in water, at room temperature, with low catalyst loadings (2-16 mol%).

Conjugate Additions of Amines to Maleimides via Cooperative Catalysis

A cooperative system comprising of a lithium Lewis acid and amine base significantly enhances the rate of the conjugate addition of a wide array of amines to maleimides. This operationally simple, scalable method provides mono-addition products in high yields and purity. This conjugation was successfully applied to the kinase inhibitor crizotinib in a chemoselective ligation to create novel fluorescent probe. (Figure presented.).

Small-sized human immunodeficiency virus type-1 protease inhibitors containing allophenylnorstatine to explore the s2? pocket

A series of HIV protease inhibitor based on the allophenylnorstatine structure with various P2? moieties were synthesized. Among these analogues, we discovered that a small allyl group would maintain potent enzyme inhibitory activity compared to the o-methylbenzyl moiety in clinical candidate 1 (KNI-764, also known as JE-2147, AG-1776, or SM-319777). Introduction of an anilinic amino group to 2 (KNI-727) improved water-solubility and anti-HIV-1 activity. X-ray crystallographic analysis of 13k (KNI-1689) with a beta-methallyl group at P2? position revealed hydrophobic interactions with Ala28, Ile84, and Ile50? similar to that of 1. The presence of an additional methyl group on the allyl group in compound 13k significantly increased anti-HIV activity over 1 while providing a rational drug design for structural minimization and improving membrane permeability.

Chiral amplification based on enantioselective dual-phase distribution of a scalemic bisoxazolidine catalyst

A readily available bisoxazolidine ligand was found to catalyze the asymmetric alkylation of aldehydes with Et2Zn and less reactive Me2Zn, providing high yields and ee’s in both reactions. The bisoxazolidine-catalyzed alkylations and alkynylation of benzaldehyde show a positive nonlinear effect that cannot be accounted for by Kagan’s MLn model. The chiral amplification originates from selective phase distribution favoring enrichment of the major enantiomer of the scalemic catalyst in solution.
