Research Abstract |
A new dirhodium(II) carboxylate complex [Rh_2(S-TBPTTL)_4] is an exceptionally effective catalyst for enantioselective cyclopropenation reactions of 1-alkynes with 2,4-dimethyl-3-pentyl α-alkyl-α-diazoacetates in preference to alkene formation via a 1,2-hydride shift, in which exceptionally high levels of asymmetric induction (up to 99% ee) as well as good to high chemoselectivities have been achieved.
