J. Mattay et al., PHOTOINDUCED CYCLOADDITIONS AND CYCLIZATIONS - MECHANISTIC STUDIES AND SYNTHETIC APPLICATIONS, Journal of information recording, 23(1-2), 1996, pp. 23-29
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.
