Equation presented. The racemic or enantioselective allylation of in situ formed β,γ-unsaturated aldehydes provides efficient access to bishomoallylic alcohols from readily available 2-vinyloxiranes. These products, when subjected to modified Grubbs cross

(matrix presented) 2-Vinyloxiranes have been found to be excellent surrogates to β,γ-unsaturated aldehydes. These valuable electrophiles, generated in situ by treatment of a 2-vinyloxirane with a catalytic amount of Sc(OTf)3, are effectively tr
An asymmetric synthesis of (+)-grandisol, a constituent of the aggregation pheromone of the cotton boll weevil, via a kinetic resolution

A novel approach to the asymmetric synthesis of (+)-grandisol, (1R,2S)-isopropenyl-1-methylcyclobutaneethanol, involves the use of catalytic kinetic resolution of a primary allylic alcohol, [(1RS,5SR)-5-methylbicyclo[3.2.0]hept-2-en-2-yl] methanol. The allylic alcohol is prepared in four steps from simple achiral materials involving the use of a modified Shapiro reaction. The resolved alcohol (95% ee) is then reduced in two steps to the corresponding methyl alkene, (1S,5R)-2,5-dimethylbicyclo[3.2.0]hept-2-ene. This alkene is converted to (+)-grandisol (95% ee), in three steps, by modified literature procedures.
A convenient synthesis of vinyl epoxides from glycidic esters via α-hydroxy-β,γ-unsaturated esters

Glycidic esters, upon isomerisation with BF3.ET2O yield α-hydroxy-β,γ-unsaturated esters. These are then reduced with LiAlH4 to vicinal diols which are converted to vinyl epoxides in two steps.
