Facile, versatile, and cost-effective synthetic routes for the preparation of a range of new 3-alkyl-, 4-alkyl-, 3,4-dialkyl-, and 3-halo-4-alkyl-2,2′-bipyrrole-5-carboxaldehydes have been developed. These 2,2′-bipyrrole-5-carboxaldehydes offer interesting potential as building blocks for making bioactive natural and unnatural products, as demonstrated by the synthesis of B-ring functionalized prodiginines
已经开发出用于制备一系列新型 3-烷基-、4-烷基-、3,4-二烷基-和 3-卤代-4-烷基-2,2′-联吡咯-5-甲醛的简单、多功能和具有成本效益的合成路线。这些 2,2′-联吡咯-5-甲醛作为制造生物活性天然和非天然产物的构建块具有有趣的潜力,正如 B 环官能化 prodiginines (PG) 和 tambjamines 的合成所证明的那样。
