Abstract
Photocycloadditions of aromatic aldehydes 2a-e With cyclic ketene sily l acetals 1a-e have been investigated. Regio- and exo-selective format ion of the bicyclic 2-alkoxyoxetanes 3 was observed in high yields. Hy drolysis of the acidlabile oxetanes 3 with neutral water was efficient ly achieved to give aldol type adducts 4 (threo-selective formations).
