It was found that thioboronite reacted with substituted ketene (produced from α-haloacyl halide and zinc dust) and carbonyl compounds to give the corresponding α-substituted β-hydroxyalkanethioates in good yields. Also, it was established that β-hydroxyalkanoates were obtained in good yields by utilizing aluminum alkoxide in place of thioboronite in the above reaction.
