Abstract
DOI: 10.1134/S1070363207070250 It was shown previously that 2-benzoylamino-3,3dichloroacrylonitrile (I) and its analogs are valuable reagents for heterocyclizations leading to derivatives of mononuclear and condensed heterocycles [1 7]. In our systematic research on such cyclizations we have found two simple transformation sequences I II IV and III III V leading to new derivatives of 5-amino-1,3-oxazole (see scheme).
