The Beckmann fragmentation is one of the long-known reacnons and used widely in organic syntbesis.l The reactive intermediates 2 in the Beckmann fragmentation of the corresponding a-alkoxycycloalkanone oxime denvatives are very active electrophdes. Although they seem to react with many kinds of nuc
An efficient radical cyclisation-Beckmann fragmentation and a Beckmann fragmentation-radical cyclisation strategy for the synthesis of a [4.3.3]propellane derivative is described.
