A SYNTHESIS OF ALKYNYL AZACYCLOALKANES BY THE COUPLING REACTION OF ALKYNYL BORANES AND LACTAMS
Yamaguchi, Masahiko,Hirao, Ichiro
, p. 1719 - 1722 (1983)
Alkynyl azacycloalkanes are synthesized in good yiels by the addition reaction of alkynyl boranes to lactams followed by a lithium aluminium hydride reduction of the adducts.
