One-pot synthesis of substituted 3-amino-2-nitrothiophenes and selenophenes
摘要:
In this work, we described an easy preparation of substituted 3-amino-2-nitrothiophenes and selenophenes. Substituted beta-chloroacrylonitriles were reacted with sodium sulfide or sodium selenide and bromonitromethane to yield the expected compounds in a one-pot three-step procedure in good yields.

2-(3',4',5'-Trimethoxybenzoyl)-3-amino-5-aryl/heteroaryl thiophene derivatives were synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization, and cell cycle effects. SARs were elucidated with various substitutions on the aryl moiety 5-position of the thienyl ring. Substituents at the para-position of the 5-phenyl group showed antiproliferative activity in the order
Substituted 7-hydroxythieno[3,2-b]pyridin-5(4H)-ones were prepared from the corresponding β-chloropropenonitriles in one step.
