An advanced intermediate for the heterocyclic aminal core of zoanthaminelnorzoanthamine alkaloids was prepared in an enantio and stereoselective manner. Contiguous quaternary chiral centers were selectively constructed utilizing a stereoselective cuprate addition to the readily available (+)-Wieland-Miescher ketone.
以对映体和立体选择性的方式制备了先进的中间体,用于制备藏菊胺基间氮杂胺生物碱的杂环氨基核。利用立体选择性铜酸盐添加到容易获得的(+)-Wieland-Miescher酮中,选择性地构建连续的四元手性中心。
