茉莉酮和二氢茉莉酮是一类名贵香料,研究这类化合物的合成方法一直是人们感兴趣的问题。已有许多报道,其中包括甲基乙烯基酮和庚醛或1-硝基庚烷进行Michael加成得到1,4-二酮进行分子内缩合成的二氢茉莉酮。本文报道一种从甲基乙烯基酮和1-己烯经过2-己基-5-甲基-1,2-氧硼杂环戊烷中间
Jasmone and dihydro jasmone are a class of valuable spices, and the synthesis of these compounds has always been a topic of interest. There have been many reports, including methyl vinyl ketone and heptanal or 1-nitroheptane Michael addition to 1,4-diketone intramolecular condensation of dihydro jasmone. This paper reports a methyl vinyl ketone and 1-hexene 2-hexyl-5-methyl-1,2-oxaborolane intermediate
