摘要

Eliel'l observed for the methyl analogues of 6 and 30, ring opening predominates in five- membered rings and dealkylation in six-membered rings. The dealkylation reaction using 1, 4-thioxane as the alkyl carrier should permit the ready transfer of any primary alkyl group. To promote ring opening in six-membered rings, the desired SN2 reaction was enhanced by making it an allylic displacement as in 8. The geometrical requirements for this process ...
