A STEREOCONTROLLED SYNTHESIS OF 2-METHYL-2-ALKENENITRILES FROM C-METHYL-C,N-BIS(TRIMETHYLSILYL)KETENIMINE AND ALDEHYDES

Abstract
A stereocontrolled synthesis of 2-methyl-2-alkenenitriles is achieved via the diastereoselective aldol type reaction of C-methyl-C,N-bis(trimethylsilyl)ketenimine with aldehydes in the presence of a mixture of TiCl4 and Ti(O-iPr)4.
