Harwood, Laurence M.,Kitchen, Lara C.
, p. 6603 - 6606 (1993)
Due to steric contraints imposed upon the bridging chain by the three-carbon linear unit associated with the alkyne, hex-5-ynal condenses with (5R)-phenylmorpholin-2-one (1) and undergoes intramolecular 3+2 dipolar cycloaddition via the syn-azomethine yli
