The regiospecific metal–ammonia reductions of both cis-8-hydroxy-7,11,11-trimethylspiro[5·5]undeca-1,4-dien-3-one (2a) and its metal alkoxides (2b) and (2c) could be achieved as a result of the proximity of the hydroxy-group to afford t-8-hydroxy-t-7, 11, 11-trimethyl-(6rC1)-spiro[5·5]undec-1-en-3-one (4) in high yield.
顺式-8-羟基-7,11,11-三甲基螺[5·5] undeca-1,4-dien-3-one(2a)及其金属醇盐(2b)和(2c)的区域特异性金属氨还原)的产生是由于羟基的接近产生了t -8-羟基-t -7,11,11-三甲基-(6 r C 1)-螺[5·5] undec-1- en-3-one(4)高产。
