4--Chloromethyiene-2-ph~yl-5(4H)-oxazolone 1 was used as the starting material for the preparation of a series cf 4-ylideneoxazolones 3 by the Stille reaction. When compound 1 was reacted with organostannanes 2 in the presence of the palladium caUdyst, OXaZ~OB~ 3 w~re oblailgd in good yields in mild
We report a new reaction by which novel bicycle (3.3.1) nonane-2,9dione and 2-substituted tetrahydro-l-azaindan-3-ones can be prepared conveniently. This reaction which takes place between enamines derived from cyclohexanone and 4-benzylidene 5-oxazolones was carried out in dry benzene, from which t
