Palladium-catalyzed chemoselective decarboxylative cross coupling of benzoic acids with α-oxocarboxylic acids was realized via an arene sp2 C–H functionalization process. This work represents the first example of transition-metal-catalyzed cross-coupling reactions with two acids acting in different roles. The syntheticutility of this method was confirmed by the synthesis of pitofenone, an antispasmodic

A synthetic protocol to isoindoles is reported through one-electronreductions of dibenzo[1,4]diazocines. The utility of the approach has been demonstrated through the synthesis of six novel isoindole derivatives. Photophysical measurements revealed emissions between 440 and 460 nm. A reaction mechanism, supported by experimental results and quantum chemical calculations, is postulated.
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
