Regioselective synthesis of 4 '-amino-1 ' H-spiro[cyclohexane-1,2 '-(pyrimido [1,2-albenzimidazole)]-3 '-carbonitrile in aqueous medium

Record type: Article

A simple, mild and environment-friendly procedure for synthesis of 4'-amino-1'H-spiro[cyclohexane-1,2'-(pyrimido[1,2-a]benzimidazole)]-3'-carbonitrile is developed using microwave irradiation in water. The product is obtained in short time, in excellent yield, and in a good state of purity. The reaction pathway and the influence of reaction conditions on regiochemistry are also investigated. The regioselectivity in this process is confirmed chemically and by single-crystal X-ray molecular structure determination.
