Ruthenium-Catalyzed Enantioselective [3+3] Cycloaddition of Propargylic Alcohols with 2-Naphthols
摘要:
Ruthenium-catalyzed enantioselective [3+3] cycloaddition of propargylic alcohols with 2-naphthols affords the corresponding cycloaddition products in moderate to good yields with a high enantioselectivity (up to 99% ee). This cycloaddition proceeds via stepwise reactions of propargylation and intramolecular cyclization, where ruthenium-allenylidene and -vinylidene complexes work as reactive intermediates, respectively.
