摘要

Abstract: Photolysis of several 1-acylcycloalkenes has been investigated and found to lead to three types of rearrangement. Simple ketones 1-5, as well as 22, undergo hydrogen transfer with formation of spiroketones 7-11 and 23 plus some minor products. Cyclohexenyl ketones 25 and 29 give the hexahydrofuorenones 27 and 28 in an electrocyclic reaction, and the doubly unsaturated 35 is isomerized to ketene 43 which can be isolated as esters ...
