Abstract
Synthetic applications and mechanistic studies from three areas of pho toinduced cycloadditions and cyclizations are reported: First it is sh own that unsaturated silyl enol ethers preferentially cyclisize in a 6 -endo mode via their photochemically generated radical cations. In the following chapter we discuss fragmentation-cyclization reactions of u nsaturated alpha-cyclopropyl ketones by photoinduced electron transfer leading to polycyclic compounds. Finally a kinetic and theoretical st udy of [2+3] cycloadditions of nitrile ylides generated from 2H-azirin es is presented.
