Catalytic Enantioselective Intermolecular Hydroacylation: Rhodium-Catalyzed Combination of β-S-Aldehydes and 1,3-Disubstituted Allenes
摘要:
A rhodium(I) catalyst incorporating the Me-DuPhos ligand promotes enantioselective intermolecular hydroacylation between P-S-aldehydes and 1,3-disubstituted allenes. The nonconjugated enone products are obtained in good yields and with high enantioselectivities.

Herein we report a Rh(I)-catalyzed two carbon insertion into C–C bonds of benzocyclobutenols by employing symmetrical and unsymmetrical allenes. This reaction provides rapid access to alkylidene tetralins bearing two adjacent stereogenic centers in good yields and diasteroselectivities.
