摘要

Abstract Propanedinitrile reacts with acyloins I-III to give 2-amino-3-cyano-4, 5-disubstituted furanes IV-VI; the latter react with formamide to give 4-amino-5, 6-disubstituted furo [2, 3-b] oyrimidines VII-IX. The derivative IV reacts with acetanhydride to 2-acetylamino-3-cyano-4, 5- di (2-furyl) furane (X), and aminofurane VI reacts with acetanhydride to give 2-(N, N- diacetylamino)-3-cyano-4, 5-diphenylfurane (XI). With aldehydes the aminofuranes IV-VI ...
