An efficient synthesis of the side-chain precursor crucial to the preparation of 18-methoxycoronaridine (18-MC) has been developed. This procedure represents an improvement upon the original synthesis, in which regioisomers were separated by chromatography to provide the requisite precursor. Incorporation of the protected primary alcohol moiety in the early stages of the synthesis provides the requisite regioisomer unambiguously and obviates the need for chromatography at any point.
对制备 18-甲氧基可可碱(18-MC)至关重要的侧链前体的高效合成方法已经开发出来。这种合成方法改进了原来的合成方法,即通过色谱法分离regioisomers来提供所需的前体。在合成的早期阶段加入受保护的伯醇分子,可以明确地提供所需的区域异构体,而无需在任何阶段进行色谱分析。
