✦ Synopsis


Organovanadium compounds generated in dichloromethane from equimolar amounts of vanadium trichloride and Grignard reagents underwent the chemoselective cross-coupling reaction with acid chlorides leading to the

Sulfinyldiacetic acid amide ester rac-1 was efficiently synthesized starting from thiodiacetic acid 4. Treatment of rac-1 with Ac 2 O and TMSOTf in CH 2 Cl 2 at -40Β°C gave chemoselectively amide site a-acetoxy sulfide rac-2 in a ratio (91:9) of rac-2 and rac-3 and in a 90% total yield. Similar treat
