英文摘要
(1) Asymmetric intramolecular cycloaddition of carbonyl ylides derived from indolyl-substituted α-diazo-β-ketoesters under the influence of Rh2(S-TCPTTL)4 provided cycloadducts in up to 90% ee and with perfect endo diastereoselectivity.(2) Asymmetric intermolecular cycloaddition of carbonyl ylides derived from trichloroethyl esterpossessingα-diazo-β-ketoesters with N-methylindole using Rh2(S-TCPTTL)4 gave a 96:4 mixture of exo- and endo-cycloadducts in 96% yield with 97% ee for exo adduct.
