Use of Functionalised Ynamines in a Hetero-Diels-Alder Approach to Dihydronaphtholpyrans and Indenopyrans

Reaction of the ynamine ester methyl 3-(pyrrolidin-1-yl)prop-2-ynoate 5 with 2-(4-nitrobenzylidene)-1-tetralone 1 results in a very poor yield of the chromatographically labile 4-aryl-5,6-dihydro-4H-naphtholpyran 8 along with the α-pyrone 10.Increa
