A novel palladium-catalyzed asymmetric cyclocarbonylation of allylic alcohols to γ-butyrolactones
A catalyst system based on [Pd2(dba)3]·CHCl3/(-)-BPPM has been found to effect asymmetric cyclocarbonylation of certain prochiral allylic alcohols to produce good yields of optically enriched γ-butyrolactones. The reaction
Intramolecular Diels-Alder Cycloadditions of Perchloro(allyloxy)- and Perchlorobis(allyloxy)cyclopentadienes
The intramolecular cycloadditions of some mono(allyloxy)- and bis(allyloxy)perchlorocyclopentadienes have been carried out.Even in the case of trisubstituted olefins, this internal cycloaddition process occurs in good yield.The allyloxy compounds (10, 11,
