摘要

Dechlorination of V with sodium-THF-t-butyl alcoholg afforded the unsaturated ketal VII17 in 70 yield. The nmr spectrum of this compound showed relatively shielded olefinic protons at T 4.30, characteristic of the endo-tricyclo [3.2. 1. 02, 4] octene sy~ tem.~?'~ In addition, the spectrum did not reveal any unusual deshielding of a cyclopropyl methylene hydrogen by the bridge methoxyls which would be expected of an exo configuration. 11 Catalytic ...
