The direct conversion of beta-hydroxyproline derivatives into 5-hydroxypyrazin-2(1H)-ones under Mitsunobu conditions has been discovered to be a general biomimetic protocol generating IMDA intermediates and has been applied to the concise, biomimetic total syntheses of D,L-stephacidin A and D,L-brevianamide B.
已发现在Mitsunobu条件下将β-羟基脯氨酸衍生物直接转化为5-羟基吡嗪2(1H)-酮是生成IMDA中间体的一般仿生方法,已被用于D,L-的简洁,仿生总合成中Stephacidin A和D,L-brevianamideB。
