The regioselective title reaction between vinyl benzoxazinanones and aryl, alkenyl or alkyl substituted enals delivers benzazepine derivatives in high yields, with high diastereo- and excellent enantioselectivities. [ABSTRACT FROM AUTHOR]

A novel N-heterocyclic carbene-catalyzed regiodivergent annulation reaction of N-iminoisoquinolinium ylides with enals is studied. [ABSTRACT FROM AUTHOR]

Various 1,2-diazepine derivatives are synthesized by regio- and enantioselective formal [4 + 3] annulation reaction between enals and in situ formed azoalkenes. [ABSTRACT FROM AUTHOR]

The process is applied to various azaaurones and α,β-unsaturated aldehydes to afford indole-based spiro compounds with a quaternary stereogenic center. [ABSTRACT FROM AUTHOR]

The article presents the chemical steps involved in the biomimetic asymmetric 1,3-dipolar cycloaddition.

This method uses a chiral primary amine and a chiral phosphoric acid as an organocatalytic system to yield the products (III) with high enantioselectivities. [ABSTRACT FROM AUTHOR]

The title reaction of 3,3′-bisindolin-2-ones with vinylcarbamates catalyzed by a chiral phosphoric acid affords the corresponding indolinones with concomitant generation of an all-carbon quaternary stereogenic center in high yield and excellent enantioselectivity. [ABSTRACT FROM AUTHOR]
