Asymmetric Intermolecular Hydroacylation Reactions of Alkenes and Allenes

3 Asymmetric Intermolecular Hydroacylation Reactions of Alkenes and Allenes 

Notably, the sulfur atom was necessary for reaching high reactivity because the reaction involving an analog of 44 with the sulfur atom being replaced by a methylene moiety was very sluggish. Only less than 5% conversion was achieved after the reaction proceeded for 4 days under the optimal conditions.
