[1,2]-Wittig rearrangement of acetals. Part 2: The influence of reaction conditions
摘要:
Acetals of seven alcohols with (+)-camphor derived enantiomerically pure 7,8,8-trimethyl-4,7-methanobenzofuran-2-ol were subjected to different reaction conditions favorable for a [1,2]-Wittig rearrangement. Results with regard to conversion, yield and stereochemical course depending on the reaction conditions are discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
