Solid Supported Synthesis of Bio-Active Dimeric Alkylene and Diketoalkylene 9H-Carbazole Compounds Via Greener Methodology

H. P. Narkhede

9H-carbazole readily reacts with dibromoalkane/acid di chloride after adsorption on solid supports and irradiation with microwaves, to afford the corresponding products in good yields. The method was found to be satisfactory for resolution of pure products, in a shorter time as compared to the conventional method. The additional features of methodology include very faster and solvent free reaction, easy work-up, higher yields and purity of the products and thus ecofriendly approach.
