Thiophene Derivatives

Some differently substituted 4-phenylthiophene derivatives 2a-d and 8a, b have been prepared from α-substituted-β-thiocyanatomethyl cinnamonitrile (1). The thiophene derivatives 2a, b and 8a react with trichloroacetonitrile and formamide to afford thieno[2,3-d]pyrimidine derivatives 4, 5 a-c, 7 and 9 a-c, respectively.

Substituted Pyrroles

Several new 3-aminopyrrole derivatives have been synthesized from 3-substituted amino-2-phenylacrylonitriles using Thorpe-Ziegler cyclization. These substituted pyrroles are readily converted into 5H-pyrrolo[3,2-d]pyrimidines (9-deazapurines).
