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