摘要

我们合成了一系列含有单萜分子和 l-脯氨酸或 l-苯丙氨酸残基的双脒共轭物。合成的双脒能催化苯甲醛与二乙基锌的不对称乙基化反应。具有 (-)-α蒎烯和叔丁氧羰基-l-脯氨酸的双脒在加成反应中实现了最高的对映选择性（ee 24%）。

The first non-symmetrically substituted conjugates of bispidine with monoterpenoids and amino acids. Synthesis and application for catalysis of addition of diethylzinc to aldehydes

A series of bispidine conjugates bearing monoterpene moieties and either l-proline or l-phenylalanine residues was synthesized. The synthesized bispidines can catalyze asymmetric ethylation of benzaldehydes with diethylzinc. The highest enantioselectivity of the addition reaction (ee 24%) was achieved for bispidine with (–)-α-pinene and Boc-l-proline moieties.
