摘要：

Ritter reaction of podophyllotoxins with chloroacetonitrile and subsequent cleavage of the chloroacetyl group in the resulting chloroacetamide with thiourea under both classical heating and ultrasonic conditions is an efficient procedure for the synthesis of 4 beta-aminopodophyllotoxins. In general, significant improvements in the rates of reaction and yields of the sonochemical reactions relative to the classical heating reactions were observed.
