Ringopening of 3-Substituted 2,3-Epoxynitriles under Acetylating Conditions
Althoff, Wolfgang,Tinapp, Peter
, p. 289 - 294 (2007/10/02)
The reactivity of 2,3-epoxynitriles 1 towards various acetylating agents was studied.Depending on the reaction conditions, 2,3-diacetoxynitriles 2, 2-acetoxy-3-chloronitriles 5 or enol acetates of α-ketonitriles 3 are formed as main products.
