Photochemical reactions of stereoisomeric 7,7,8,8-tetramethylbicyclo[4.2.0]octan-2-ones
Abstract
Photochemical reaction of the trans-fused bicyclic ketone (1) in solution gave the unsaturated aldehyde (4), whereas irradiation of the cis-fused isomer (2) in methanol led to inefficient photoreduction.
