Synthesis of 3E-tetradecenol, 3E, 9E-tetradecadienol, and their acetates starting from acetylcyclopropane
摘要:
Stereospecific synthesis of the linear E-olefins mentioned in the title was realized by a general scheme that was worked out earlier by the authors and which includes as key steps homologization of the corresponding aliphatic pentakisnoraldehydes by means of trimethylsilyloxyvinylcyclopropane and ZnBr2-initiated rearrangement of the intermediate cyclopropylcarbinols under the influence of Me3SiBr.
