2-vinylpyrroles and pyrrolo[3,2-d]pyrimidines from direct addition of aldehydes to 4-amino-pyrrole-2-carboxylate derivatives
Fridkin, Gil,Lubell, William D.
scheme or table, p. 849 - 852 (2009/04/07)
A new methodology for the direct preparation of 2-vinylpyrroles is presented. Treatment of 4-amino-pyrrole-2-carboxylates 5a-c and 6a-d with aliphatic aldehydes and TFA furnished 2-vinylpyrroles 2a-k in 9-87% yields. Under similar conditions ureidopyrroles 5a-c reacted with aryl aldehydes to provide pyrrolo[3,2-d]pyrimidines 1a-d in 28-63% yields.

(Matrix presented) A series of 4-amino-1H-pyrrole-2-carboxylic acid benzyl esters has been synthesized in 61-84% yields on treatment of N-PhF-4-oxoproline benzyl ester and its 3-alkyl-substituted derivatives with different primary and secondary amines and
