Rm. Corbett et al., APPLICATION OF THE OXA-DI-PI-METHANE PHOTOISOMERIZATION IN THE REARRANGEMENT OF CARBOCYCLES POSSESSING BRIDGEHEAD UNSATURATION, Tetrahedron, 53(32), 1997, pp. 11099-11108
Studies directed toward an application of the oxa-di-pi-methane (ODPM)
photoisomerization to convert a bicyclo[4.4.1] undecene (i) to a bicy
clo[5.3.1]undecene (3) are described. This transformation, which is eq
uivalent to a 1,2-acyl shift, could find utility in the synthesis of b
ioactive natural products possessing bridgehead unsaturation. (C) 1997
