Synthesis of pyrrole urea and pyrrole carbonylurea derivatives

Tetrahedron, 2009
Abstract A series of urea and carbonylurea distamycin analogs whereby the linker has two NH groups for hydrogen bonding with base pairs of DNA were synthesized. The urea and carbonylurea derivatives are prepared from the in situ generation of pyrrole isocyanate (prepared from compound 3 ) and acyl isocyanate (compound 9 ), followed by the reaction ...

Synthesis of pyrrole and substituted pyrroles (Review)

2017
Pyrrole is widely known as a biologically active scaffold which possesses a diverse nature of activities. The combination of different pharmacophores in a pyrrole ring system has led to the formation of more active compounds. Pyrrole containing analogs are considered as a potential source of biologically active compounds that contains a significant set

Pyrrole chemistry. XXVII. 2,3,4-Trisubstituted pyrroles and a second synthesis of porphobilinogen from pyrrole

Canadian Journal of Chemistry, 1984
Changes in some of the key intermediates and procedures used in our earlier total synthesis of porphobilinogen from pyrrole that improve the yield to 11% are reported. Ethyl pyrrole-3-acetate was formylated by the Vilsmeier–Haack method and then iodinated.
