oxotitanium. A Chemoselective and Efficient Catalyst for Aldol-type Reaction of Ketene Silyl Acetals with Aldehydes

Article abstract of DOI:10.1246/cl.1989.1909

In the presence of catalytic amount of <1,2-benzenediolato(2-)-O,O'>oxotitanium, ketene silyl acetals smoothly react with aldehydes to afford the corresponding β-hydroxy carboxylic esters in good yields under mild conditions.According to this procedure, a
