Furans from novel [3+2] photocycloaddition of alkenes to 2-(1-alkynyl)cyclohexenones
Margaretha,Reichow,Agosta
, p. 5393 - 5396 (2007/10/02)
Photocycloaddition of 2-alkynyl-substituted cyclohexenones 8c-11c with isobutylene (2) and tetramethylethylene (3a) leads to tricyclic furans 15a-18a and 15b-17b, respectively, in gas chromatographic yields of ~90%. A suggested mechanism for this novel pr
