Reactions of Trimethylsilyl Ketene Acetals with Benzoyl Cyanide and with α-Keto Esters
Reddy, Chaganti P.,Tanimoto, Shigeo
, p. 411 - 414 (2007/10/02)
Trimethylsilyl ketene acetals reacted with benzoyl cyanide in the absence of a catalyst to give N-trimethylsilyl-β-benzoyl-β-iminopropionates.In the presence of a Lewis acid catalyst they gave the corresponding α-benzoylcarboxylates in moderate yields.Sev
