在艾伦·弗朗西斯·托马斯(Alan Francis Thomas)首次发现五十年之后,我们描述了一种多用途,无金属且无压力的多米诺-克莱森-科普重排方法,它使用易于获得的α,β-不饱和醛5或其缩醛5'和烯丙基醇6进行重排。通过这种转换,可以方便地访问大量的辐射柑橘和花香的玫瑰味气味剂。气味新颖花香红润和柑橘醇的型材13,14,和16进行了研究。化合物14ba具有花香,玫瑰色,天竺葵般的特征,并具有独特的性能和扩散性。复合16ba具有清晰的主要柑橘香气特征,具有干净的绿色葡萄柚/大黄成分。两种香精最近已成功引入Rosyfolia ™(14ba)和Pomelol ™(16ba)香水中。
In tandem reactions, cyclopropylcarbinols are obtained from allyloxylithium or -magnesium intermediates, generated in situ by alkylation of conjugated aldehydes, ketones, and esters as well as from allyl carboxylates or vinyloxiranes. Using this methodology, numerous fragrance ingredients and their precursors were efficiently converted to the corresponding cyclopropylcarbinols.
