Herein, the first enantioselective total synthesis of a number of biologically relevant (−)-epicatechin conjugates is described. The success of this synthesis relied on (i) optimized conditions for the stereospecific cyclization step leading to the catechin C ring; on (ii) efficient conjugation reactions; and on (iii) optimized deprotection sequences. These standard compounds have been subsequently
在此,描述了许多生物学上相关的(-)-表儿茶素结合物的第一对映选择性全合成。该合成的成功取决于(i)导致儿茶素C环的立体有择环化步骤的最佳条件;(ii)有效的共轭反应;(iii)优化的脱保护序列。随后,这些标准化合物首次用于阐明在(-)-表儿茶素吸收后存在于四种不同人类生物液中的(-)-表儿茶素结合物的模式。
