Abstract:A model of ring A of vernolepin is synthesized by 1,4-fragmentation of γ-thiyl and γ-stannyl alkoxy-radicals, generated by photolysis of the corresponding δ-lactols (4) and (5) in the presence of iodosobenzene diacetate and iodine. It should be pointed out that the δ-lactone ring and the angular vinyl group are introduced in one step.
Description:4 pages, 1 table, 2 schemes.
