easily and efficiently from inexpensive and commercially available substrates. We tested this class of alkaloids in the alkylation of glycine derivative, carried out under phase-transfer catalyst conditions. The presented hybrid catalysts offer both high reaction yields (up to 97%) and high enantioselectivities of the obtained product (up to 94% ee).
本文中,我们以季铵盐的形式提供了金鸡纳生物碱的简单酰胺衍生物的文库。所获得的衍生物可以很容易和有效地从廉价的和可商购的基质中产生。我们在相转移催化剂条件下进行的甘氨酸衍生物烷基化反应中测试了这类生物碱。所提出的杂化催化剂提供了高的反应产率(高达97%)和所获得的产物的高的对映选择性(高达94%的ee)。
