Abstract Squaricacid, a green, metal-free and eco-friendly organocatalyst, has been exploited for the synthesis of biologically interesting 2,3-dihydro-1H-perimidines. The reaction was performed using water as a green reaction medium and the organocatalyst can be easily recovered and reused up to four consecutive cycles without much decrease in catalytic activity. Several advantages of the present

8-diaminonaphthalene in the presence of CMK-5-SO 3 H as a reusable and eco-friendly catalyst (Scheme 1). composite was filtrated and washed with EtOH and acetone to remove excess and unpolymerized FA. The obtained composite was heated to 850 °Cunder vacuum at a ramp of 10 °C/min for 3 h to carbonization. Ordered mesoporous carbon (CMK-5) was obtained by removal of silica by HF (10 % in 1 : 1 EtOH - H 2 O), washed
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.
