Stereoselectivity in the Photoinduced Electron Transfer (PET) promoted intramolecular cyclisations of 1-alkenyl-2-silyl-piperidines and -pyrrolidines: Rapid construction of 1-azabicyclo[m.n.0] alkanes and stereoselective synthesis of (±)-isoretronecanol and (±)-epilupinine

PET promoted cyclisations of 1-alkenyl-2-silyl-pyrrolidines and -piperidines 9a-d to 1-aza-bicyclo[m.n.0]alkanes have been found to be stereoselective. The five-membered ring formation gives predominantly cis products while six-membered rings are trans. Application of such cyclisations to the synthesis of (±)-isoretronecanol 22a, (±)-epilupinine 29 and related alkaloids has been demonstrated. Copyright 1996 by the Royal Society of Chemistry.

Stereoselectivity in the cyclisation of photoinduced electron transfer (PET) generated cyclic α -amino radicals: First general stereoselective entry to 1-azabicyclo (m:n:o) alkane systems

Stereoselectivity in the intramolecular cyclisation of PET-generated cyclic α-amino radicals and its application to the synthesis of 1-azabicyclo (m:n:o) alkane systems is reported.
