  An efficient method for the synthesis of substituted 2,3-dihydro-1H-perimidine derivatives is described using bis(oxalato)boric acid (HBOB) as catalyst. The methodology provides an easily handled and recyclable catalyst for this type of reaction as an alternative platform to the conventional acid-catalyzed thermal processes. The time required to complete the reaction using HBOB was found to be shorter than conventional methods. Recycling of the catalyst has been efficiently achieved using a simple procedure.

  日期：2014.12

  An efficient protocol has been developed to synthesize various dihydro-1H-perimidine derivatives using commercially available Amberlyst-15 as a catalyst. Dihydro-1H-perimidine derivatives are potential candidates for pharmaceutical and high tech applications. The conspicuous features of this protocol are short reaction time, compared to higher product yield, easy recovery, reusability and regeneration of catalyst. The reaction was successfully scaled up to gram level, which reflects the practicability of the present protocol. (C) 2014 Elsevier B.V. All rights reserved.
