An efficientmethod for the synthesis of spiro-N,O-ketals with 5- and 6-membered rings was developed via a gold-catalyzed spiroamidoketalization of alkynyl amidoalcohols under mild conditions. This methodology has been successfully applied to the synthesis of a spiro-N,O-ketal analogue of marineosin A.
The present invention relates to herbicidally active thiadiazole derivatives, as well as to processes and intermediates used for the preparation of such derivatives. The invention further extends to herbicidal compositions comprising such derivatives, as well as to the use of such compounds and compositions in controlling undesirable plant growth: in particular the use in controlling weeds, in crops of useful plants.
The present invention provides fungicidal 4-substituted-3-phenyl[(heterocyclylmethoxy)imino]methyl}-1,2,4-oxadiazol-5(4H)-one derivatives of formula (I)
wherein A represents a pyridyl or thiazole group and X1, Y1 to Y5 represent independently different substituents.
