Uncatalyzed aldol reaction using a dimethylsilyl enolate and α-dimethylsilyl ester in N,N-dimethylformamide
摘要:
Dimethylsilyl enolates and alpha-dimethylsilyl esters reacted with aldehydes in N,N-dimethyl-formamide without an activator to give aldol adducts in moderate to good yields. Under the same conditions, the corresponding trimethylsilyl derivatives exhibited lower reactivities toward the aldol reaction. (C) 1998 Elsevier Science Ltd. All rights reserved.
