The total synthesis of leupyrrin B1 was accomplished by an expedient strategy that involves an optimized HATU-mediated amide coupling protocol of elaborate substrates. The generally useful procedure was also successfully applied in an improved total synthesis of leupyrrin A1. Finally, leupyrrins A1 and B1 were evaluated toward a panel of proteases, and human leukocyte elastase was discovered as a molecular
Leupyrrin B 1的总合成是通过权宜之计策略完成的,该策略涉及精心设计的底物的优化的HATU介导的酰胺偶联方案。普遍有用的程序也成功地应用于亮丙啶A 1的改进的全合成中。最后,针对一组蛋白酶评估了亮丙瑞林A 1和B 1,并发现了人类白细胞弹性蛋白酶作为亮丙瑞林的分子靶标。
