reaction of but-3-yn-2-ol dianion with 2,6,6-trimethyl-4,4-ethylenedioxy-cyclohex-2-en-1-one (1), afforded 3,5,5-trimethyl-4-(2-butenylidene)-cyclohex-2-en-1-one (4), a major constituent of Burley tobacco flavour, upon LiAlH4 reduction and hydrolysis. Vomifoliol (5) and blumenol C (6) were major by-products in this reaction.
将丁3 -yn-2-ol二价阴离子与2,6,6-三甲基-4,4-亚乙二氧基-环己-2-烯-1-酮(1)反应制得的炔二醇2,得到3,在LiAlH 4还原和水解后,白肋烟香料的主要成分5,5-三甲基-4-(2-丁烯基)-环己-2-烯-1-酮(4)。沃米弗洛尔(5)和布洛美醇C(6)是该反应的主要副产物。
