Synthesis of 3-aminopyrrolidines by cyclization of neutral C-centered α-aminoalkyl radicals
摘要:
3-Aminopyrrolidines are prepared by SmI2-promoted cyclization of neutral alpha-aminoalkyl radicals generated from N-(alpha-benzotriazolyl)alkenylamines. Appropriate manipulation of the two N-protecting groups allows further manipulation of the products, which is exemplified with the preparation of a triamide derivative. (C) 2002 Elsevier Science Ltd.
