Chemoselective alkynylation of N-sulfonylamides versusamides and carbamates – Synthesis of tetrahydropyrazines

Abstract

The chemoselective alkynylation of N-sulfonylamides versus amides and carbamates using TMS-EBX as an alkynylating agent leads to the formation of non-symmetrical tetrahydropyrazines from orthogonally protected diamines.
