J. Marcocontelles, THE HSNPH3 FREE-RADICAL MEDIATED CYCLIZATION OF 4,9-DIOXA-1,6-DODECADIEN-11-YNE, Synthetic communications, 27(18), 1997, pp. 3163-3170
We report the triphenyltin hydride radical mediated cyclization of 4,9
-dioxa-1,6-dodecadien-11-yne 2. The reaction proceeds under very mild
conditions and in good chemical yield (59%), giving a mixture of produ
cts 5 (mixture of isomers in a 1:2 ratio) and 6 (mixture of isomers in
a 1:3 ratio).
