Description and Uses

Dimethylcyanamide in the presence of tetrachlorosilane and zinc chloride is used as a promoter for one-pot, three component synthesis of a novel series of 1,3-oxazines. Being a dialkylcyanamide, it has been proved to be a more reactive substrate toward metal-mediated nucleophilic addition than alkylcyanides.
