El-Sharief, A. M. SH. published the artcileNovel synthesis and cyclization reactions of 3-amino-2-mercaptopyrrole derivatives, SDS of cas: 39267-05-5, the main research area is pyrrolopyrrolinedione preparation; pyrrolothiazole preparation; pyrrolothiazine preparation; pyrrole aminomercapto preparation cyclization; cyanothioformamide chalcone cyclization; aminomercaptopyrrole preparation cyclization chloroacetate chloroacetamide chloronaphthoquinone; isocyanate cyclization aminomercaptopyrrole; chlorobenzoyl chloride cyclization aminomercaptopyrrole.
Interaction of cyanothioformamides RNHC(:S)CN (R = Me, Et, Ph) with chalcones gave 3-amino-2-mercaptopyrroles I (R1, R2 = H, Cl, Br), which have the tautomeric structures of 3-aminopyrroline-2-thiones and 3-iminopyrrolidine-2-thiones. I reacted with chloroacetic acid, Et chloroacetate, chloroacetamide and 2,3-dichloro-1,4-naphthoquinone to give pyrrolothiazines. Reaction of I with PhN:C:O or p-ClC6H4COCl gave pyrrolothiazoles. Reaction of maleimides with RNHC(:S)CN gave pyrrolopyrrolinediones.
