The first example of the asymmetric Fujiwara-Moritani reaction catalyzed by chiral Pd(II) complexes is reported to represent a catalytic aromatic C-H bond activation-asymmetric olefin coupling reaction.

Palladium (0)-catalyzed allylic substitution reactions employing triorganoindium reagents have been investigated. In situ generated vinyl- and arylindiums react with substituted and unsubstituted cyclohex-2-enyl esters in the presence of 1-3 mol % Pd2(dba)3 to produce vinyl- or arylcyclohexenes in moderate to excellent yields. The stereoselectivity of this process was also examined, and evidence is presented that the reaction proceeds with inversion of stereochemical configuration.
SUBSTITUTION NUCLEOPHILE D'ACETATES DE CYCLENOLS ALLYLIQUES FONCTIONNELS PAR DES ORGANOMETALLIQUES EN PRESENCE DE SELS CUIVREUX. APPLICATION A UNE SYNTHESE RAPIDE DE LA (+/-) MITSUGASHIWALACTONE

Substitution of functional allylic cycloalkenol acetates by Grignard reagents (primary, secondary, tertiary-alkyl, vinyl, aryl) in the presence of a catalytic amount (2.5percent equivalent) of cuprous iodide at low temperature, gives high yields of various functional α-substituted cycloalkenes.The reaction can be applied to lithium enolates of esters and need no catalyst, but may be performed with HMPA as cosolvent.It is illustrated by a short (6 steps) and efficient total selective synthesis of (+/-)-mitsugashiwalactone from 2,5-dimethoxytetrahydrofuran with 33percent overall yield.
