Ultrasound-promoted synthesis of novel 2-imino-3-aryl-2,3-dihydrobenzo[d]oxazol-5-ol 2-iminooxazolidines derivatives

A synthesis of novel 2-iminooxazolidineswas developed by the reaction between arylcyanamides with p-benzoquinone at room temperature under ultrasound irradiation in excellent yields. Also, the chemoselective tosylation of the products were performed at room temperature under ultrasound irradiation in good yields.
