✦ Synopsis

Selective photochemical transformations of two different bichromophores incorporated in a single molecule are reported. The photochemistry of bichromophoric molecules', particularly p,y 2 -enones is the subject of many recent investigations. 4c<-Acetyl-2-carene 1 is a molecule containing not only B,y-enone system but also vinyl cyclopropane system. In such a system, three reactions viz. 1,3-acylshift (1,3 AS); oxa-di-a-methane rearrangement (ODPM, eqn-1) and vinyl cyclopropane (VCR, eqn-2) rearrangement are expected.
