Carboxylation and Mitsunobu Reaction of Amines to Give Carbamates: Retenvs Inversion of Configuration Is Substituent-Dependent. — The scope of a
47- 075 tion
mild and efficient carbamate synthesis method which involves in situ carboxylation
with carbon dioxide followed by Mitsunobu cyclodehydration, is investigated. The
cyclization proceeds with inversion of configuration in the secondary amines, while the
primary ones cyclize with retention. — (DINSMORE*, C. J.; MERCER, S. P.; Org.
