摘要：

The photochemical reactions of acetylenic ketones (1a and b) have been examined. Irradiation of 1-phenylprop-2-yn-1-one (1a) in alcohols gave 2,5-disubstituted furans (2a-d) in 18-27% yield via cyclization of the intermediate, the C-C bonded 1:1 adduct of (1a) and the alcohol, while irradiation of (1a) and NN-diethylamine in benzene gave the pyrrole (7) in 61% yield via cyclization of the intermediate, the C-N bonded 1:1 adduct of (1a) and the amine. Irradiation of 1,3-diphenylprop-2-yn-1-one (1b) and NN-dialkylamines afforded the C-C bonded 1:1 adducts (8a-c) in 30-40% yield.
