摘要

Abstract The reaction of protected 3-bromo-2-(bromomethyl)-4-methoxypyrrolo [2, 3-b] pyridine and tosylmethyl isocyanide (TosMIC) afforded a pyrido [3′, 2′: 4, 5] pyrrolo [1, 2- c] pyrimidine derivative in good yield. This compound was transformed through installation of the pyrimidine moiety in the C5 position, hydrolysis, and decarboxylation in an advanced intermediate for the total or formal synthesis of the naturalalkaloid variolin B. Reaction of 3 ...
