✦ Synopsis


A series of b-alkoxyand b-amino-a-bromoaldehydes was synthesized. The cyclocondensation of these intermediates with 2,4-diamino-6-hydroxypyrimidine yielded a series of pyrrolo[2,3-d]pyrimidines containing heteroatoms in the side chain. Choice of protecting group proved critical to the success of the bromination and cyclocondensation reactions. A number of oxygen and nitrogen protecting groups were examined and the results are described herein.

## Abstract Some fluoroaryl substituted 2‐amino‐3‐cyanopyrroles 2 were synthesized from the reaction between (2‐bromo‐1‐arylalkylidene)propanedinitriles 1 and fluoroaryl substituted aromatic amines under Gewald reaction condition, which on reaction with formamide and formic acid gave 4‐aminopyrrolo
