Abstract
Dirhodium(II) tetrakis[ N-tetrachlorophthaloyl-( S)- tert-leucinate], Rh 2( S-TCPTTL) 4, is an exceptionally effective catalyst for enantioselective tandem carbonyl ylide formation-cycloaddition reactions of 2-diazo-3,6-diketoesters with arylacetylene, alkoxyacetylene, and styrene dipolarophiles, providing cycloadducts in good to high yields and with enantioselectivities of up to 99% ee as well as with perfect exo diastereoselectivity for styrenes.
