The diverted di-pi-methane rearrangement; mechanistic and exploratory organic photochemistry.
[reaction: see text] An unusual diversion of the di-pi-methane rearrangement has been encountered. The reaction is characteristic of di-pi-methane systems having one vinyl group bearing one or two carbonyl groups and provides a synthesis of dihydrofurans.
