STEREO- AND REGIOSPECIFIC ALLYLATION OF 4-CHLOROAZETIDINONES WITH ALLYLSILANES: CONVERGENT SYNTHESIS OF A KEY INTERMEDIATE FOR (+)-THIENAMYCIN

An efficient stereospecific synthesis of optically active 4-allylazetidinones (6, 7, 11, and 15a,b) has been accomplished using silver-promoted coupling reaction of allylsilanes (5 and 14b) with 4-chloroazetidinones (3, 4, and 10a,b) derived from penicillins.
