The chiral Brønsted acid catalyzed enantioselective 1,2-addition of thiols to in situgenerated ketimines, derived from 3-hydroxyisoindolinones, has been studied. The protocol provides a variety of isoindolinone-derived N,S-ketals in up to 98% yield and up to 99% enantioselectivity. The products have been converted to a known non-nucleoside HIV-1 reverse transcriptase inhibitor and a 1,3-thiazine derivative

Selective non-nucleoside HIV-1 reverse transcriptase inhibitors. New 2,3-dihydrothiazolo[2,3-a]isoindol-5(9bH)-ones and related compounds with anti-HIV-1 activity
A series of substituted 2,3-dihydrothiazolo[2,3-a]isoindol-5(9bH)-ones and related compounds 1-73 were synthesized and evaluated for their ability to inhibit reverse transcriptase (RT) of the human immune deficiency virus 1 (HIV-1) and replication of HIV-1 in MT2 cells. The antiviral activity of these compounds depends on the stereoselective configuration of the substituent in position 9b. Structure-activity
