Cyclization of Chiral Carbon-Centered Aziridinyl Radicals: A New Route to Azirino[2',3':3,4]pyrrolo[1,2-a]indoles
摘要:
A carbon-centered aziridinyl radical has been generated from the ester of chiral aziridine carboxylic acid 5b. The resultant radical has been cyclized directly and has been brominated with CBrCl3. The bromo aziridines have also been cyclized reductively in the presence of n-Bu(3)SnH. Dihydroindole 8b bears the same relative and absolute stereochemistry as the mitomycin C nucleus.
