Abstract
The regioselective lithiation-functionalization of 2-arylazetidines has been explored. The nature of the N-substituent is mainly responsible for a regioselectivity switch. ortho-Lithiation occurred, using hexyllithium as a greener base, in N-alkylazetidines, while alpha-benzylic lithiation has been observed with N-Boc azetidines.File in questo prodotto:
