New synthesis of 2,2'-bis-delta2-oxazoline.

摘要

THIS INVENTION RELATES TO A NEW SYNTHESIS METHOD oxazoline-BISA2-2,2 '', which consists of three steps: in the first step, OXAMIDA- (HYDROXYETHYL-2) bis-N, N '' (I) it is reacted with hydrogen chloride and a nitrile of formula RCN in which R = H, alkyl, aryl, arylalkyl, alkylaryl, IN ORDER TO PRODUCE THE RELEVANT 2CLH.OXAMIDE (IMINOACILOXIETIL-2) bis-N, N '' ( II). In the second step, component (II) IS IN ORDER TO PRODUCE pyrolysate oxamide (chloroethyl-2) bis-N, N '' in the third step generates, by treatment with a base, the desired product OXAZOLINA- A2-BIS-2,2' '.
