First synthesis of methyl 3-amino-4-(het)aryl-1H-pyrrole-2-carboxylates as useful scaffolds in medicinal chemistry
摘要:
The preparation of new methyl 4-(het)aryl-3-amino-1H-pyrrole-2-carboxylates was achieved starting from commercial arylacetonitriles. This four steps synthesis afforded with good yields interesting building-blocks useful in the access to many nitrogen heterocycles with potential therapeutic interest. (C) 2004 Elsevier Ltd.

We herein describe the synthesis of novel 3-(het)aryl-pyrrolo[2,3-b]pyrrolizin-8(1H)-ones starting from commercial (het)aryl-acetonitriles. A more convergent route was also described through the first synthesis of ethyl 3-amino-4-bromo-1H-pyrrole-2-carboxylate 17. The antiproliferative activities of these compounds were tested toward various cell lines and one of them 10k shows interesting cytotoxic properties, although it was less potent than our lead compound in thiophene series 1k.
