Stereoselective synthesis of 4-oxo-2,5-dienes and conjugated dienes by Stille cross coupling reactions of vinylstannanes
(Arkat, 2007-01)
The palladium-catalyzed cross coupling reactions between trineophylstannylvinyl esters and unsaturated acyl chlorides lead mostly to 4-oxo-2,5-dienes in good yields (60-77%). In some cases homocoupling products are also ...

Conjugate systems in the construction of heterocycles and quaternary stereocenters
(2012-11-25)
The synthetic application of 4,5-bis-alkylidene-1,3-oxazolidin-2-ones led to the efficient
and regioselective synthesis of 2-(3H)-benzoxazolones and diarylamines with a short
methodology. They were also valuable synthons ...
