Synthesis of New 2-(Oxiran-2-yl)-1,3-oxazoles

详细

Reaction of 2-chloro-N-(2,2-dichloro-1-cyanovinyl)acetamide with dimethylamine gave 5-(dimethylamino)-2-[(dimethylamino)methyl]-1,3-oxazole-4-carbonitrile, where aliphatic dimethylamino group was regioselectively alkylated with iodomethane. The resulting trimethylammonium salt reacted diastereoselectively with aromatic aldehydes to form new substituted 2-(oxiran-2-yl)-1,3-oxazoles.
