A Simple Synthesis of 2′,5′-Disubstituted-Spiro [Dihydroacridine 9(10H), 4′-Thiazolines] by the Reaction of Corresponding 3-(Acridin-9-Yl)-Thioureas with Methyl Bromoacetate and Bromoacetonitrile
摘要:
A convenient method has been devised for the preparation of the spirodihydroacridinethiazolines 5a-j by the treatment of thioureas 3a-e with methyl bromoacetate and bromoacetonitrile via non-isolable isothioureas 4a-j and their subsequent cyclization with methanolic sodium methoxide.
