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

A simple two-step procedure for synthesizing functionalized benzhydrylamines is described. The first step involves a Suzuki-Miyaura coupling reaction between arylboronic acids and 3-chloro-3-arylacrylonitriles at 45 degrees C. A variety of boronic acids and substituted acrylonitriles can be used for the reaction. The resulting 3,3-diaryl-substituted acrylonitriles can be converted into their corresponding Boc-protected amines by catalytic hydrogenation.
