A practical regioselective and diastereoselective synthesis of functionalized 1-benzo[b]azepines by copper-catalyzed intramolecular cyclization has been developed. The reaction involves borylcupration of a mixture of (E/Z)-1,3-dienes, followed by capture

A chiral anion-mediated asymmetric Heck/Tsuji-Trost reaction of aryl iodides and 1,3-dienes is presented. Chiral indoline derivatives could be afforded with remarkably higher yields and enantioselectivities than our previous chiral ligand-based method. Silver carbonate is employed as both base and halide scavenger to ensure fast and recyclable exchange of the catalytic amount of chiral anions. Fast salt metathesis, as well as the acceleration effect of the chiral anion, could both benefit the stereocontrol of the reaction.

experimental part, p. 4715 - 4720 (2011/07/08)
Ionic diamine rhodium complex (1) catalyzes the reductive N-cyclization of 2-vinylnitroarenes using carbon monoxide as a reducing agent to afford functionalized indoles. The catalytic system allows direct access to indoles with ester and ketone groups at the 2- or 3-position, in good yields.
A simplified Wittig synthesis using a solid/liquid transfer process. IX. Selectivity of the condensation reaction of moderated ylides with aldehydes

, p. 1421 - 1425 (2007/10/02)
Conjugated dienes are obtained selectively and with high yields using aldehydes of various structures. The synthesis is made in a two-phase medium, i.e. solid/liquid medium.
