Chiral holmium complex-catalyzed Diels-Alder reaction of silyloxyvinylindoles: Stereoselective synthesis of hydrocarbazoles
Harada, Shinji,Morikawa, Takahiro,Nishida, Atsushi
, p. 5314 - 5317 (2013)
The catalytic and asymmetric cycloaddition between 3-[1-(silyloxy)vinyl] indoles and electron-deficient olefins gave substituted hydrocarbazoles in up to 99% yield and 94% ee. This reaction was catalyzed by a novel chiral holmium(III) complex. Alkylation of the cycloadduct gave a tricyclic compound with four continuous chiral centers, one of which was a quaternary carbon.

N -Sulfonyl- and N -acylpyrroles were synthesized via olefin ring-closing metathesis of diallylamines and in situ oxidative aromatization in the presence of the ruthenium Grubbs catalyst and a suitable copper catalyst. In the presence of Cu(OTf) 2/s
Cross metathesis of N-allylamines and α,β-unsaturated carbonyl compounds: A one-pot synthesis of substituted pyrroles
Shafi, Syed,K?dziorek, Mariusz,Grela, Karol
scheme or table, p. 124 - 128 (2011/03/20)
A tandem reaction involving cross metathesis followed by concomitant cyclisation has been developed for the synthesis of substituted pyrroles. Various protected electron-deficient N-allylamines reacted with α,β-unsaturated carbonyl compounds in the presen
