โœฆ Synopsis

Treatment of ally1 vinyl ether derivatives with organoaluminium amphoteric reagent, R3Al or R2AlSPn, results in the title reaction at room temperature under uptake of R, H, or SPh as a nucleophile on the aldehydic carbon. Lewis acid catalysis of Diels-Alder reaction' or ene reaction2 has been recently well documented. The attempted aliphatic Claisen rearrangement 3 in the presence of common acidic catalysts such as TiC14, 4 BF3, 5
