Bicyclic N,S-Acetals Containing Fused Cysteine-Amide System as New Heterocyclic Class Targeting Human Farnesyltransferase (FTase-h).

ABSTRACT: We report in this contribution the synthesis and in vitro biological evaluation of a novel class of chiral thiazoloisoindolinone scaffolds as potent inhibitors against human farnesyltransferase (FTase-h). The targeted products, sulfides (4), sulfoxides (5,6), and sulfones (7), containing up to three points of diversification, were obtained in a short-step sequence starting from the available and cost-effective L-cysteine hydrochloride (1), which is the source of N and S atoms and the chiral pool, and α-carbonyl benzoic acids (2), which are isoindolinone precursors. Concisely, the key ester intermediates (1) provide (a) sulfide-amides (4) by solvent-free amidation, (b) sulfoxides (5,6) by selective S-oxidati
