摘要

In reaction with dimethyldioxirane N-mesyl-1,3a,4,8b-tetrahydrocyclopenta[b]indoles and N-mesyl-3,3,4a,9a-tetrahydrocarbazoles mostly form the trans-epoxide. The reaction with molecular bromine leads to the product from halogenation in the aromatic ring, i.e., the corresponding N-mesyl-7-bromo-1,3a,4,8b-tetrahydrocyclopenta[b]indole or N-mesyl-6-bromo-3,4,4a,9a-tetrahydrocarbazole.
