Regioselective syntheses of polycyclic compounds by carbanion-mediated polycyclisation of olefins
Krief,Barbeaux
, p. 417 - 420 (2007/10/02)
This paper reports straightforward syntheses of 1-aryl-bicyclo-[n. 1.0]-alkanes, 1-aryl-bicyclo-[3.3.0]-alkanes and of 1-phenyl-1,4-dimethyl-cyclopentane from unsaturated benzylselenides which involve the organolithiums-mediated cyclisation of olefins and
