     “Selectivity Enhancement in the Rh(II)-Catalyzed Cyclopropanation of Styrene with (Silanyloxyvinyl)diazoacetates”
     Org. Lett. 2004, 6, 1725-1728.

The cyclopropanation of styrene with (silanyloxyvinyl)diazoacetates proceeds with exceptional diastereo- and enantioselectivity in the presence of chiral Rh(II) catalysts. 1,8-Naphthoyl-protected amino acids are the most effective Rh(II) ligands for these transformations.
