Synthesis of 2-amino-7-hydroxy-4H-chromene derivatives under ultrasound irradiation: A rapid procedure without catalyst

Synthesis of 2-amino-7-hydroxy-4H-chromene derivatives under ultrasound irradiation: A rapid procedure without catalyst

A highly efficient three-component synthesis of 2-amino-7-hydroxy-4H-chromenes by one-step condensation of aldehydes with malononitrile and resorcinol without catalyst in water under ultrasonic irradiation is described. This implies a convenient route avoiding the usage of hazardous organic solvents...
