Abstract
The reaction of alkynyl boranes, generated in situ from lithium acetyl ides and boron trifluoride etherate, with 3-benzyl-tetrahydro-1,3-oxaz ines and 1,3-oxazolidines gave the corresponding beta-aminoacetylenes in modest to good yield. By the employment of titanium acetylides to t he same reaction provided comparable results.
