of organocopper reagents to alpha, beta-unsaturated enones results in the regiospecific generation of enolateanions, which can be made to undergo the aldol reaction with (tetrahydropyranyloxy)acetaldehyde under zinc chloride catalysis. Treatment of the resulting product with p-toluenesulfonic acid in THF affords the targeted 2,3-disubstituted furan.
