摘要：

Synthetic applications and mechanistic studies from three areas of photoinduced cycloadditions and cyclizations are reported: First it is shown 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 unsaturated alpha-cyclopropyl ketones by photoinduced electron transfer leading to polycyclic compounds. Finally a kinetic and theoretical study of [2+3] cycloadditions of nitrile ylides generated from 2H-azirines is presented.
