| Abstract | A novel nanocomposite, H4SiW12O40 immobilised magnetic chitosan (HSiW-MC) was prepared via a facile procedure in one-pot fashion. This composite was fully characterised using several methods including, Fourier transform infrared spectroscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy and scanning electron microscopy. It was applied as a novel catalyst in two three components reaction involving, dimedone, differently substituted aryl aldehydes and either 3-amino-1,2,4-triazole or 2-amino benzimidazole to afford the corresponding [1,2,4]triazolo/benzimidazolo quinazolinone derivatives. It showed excellent performance in the aforementioned reaction with the high yield of 96%. Also, the effect of HSiW-MC amount, catalysts, solvents and temperatures were studied and the best results were obtained in CH3CN in the presence of HSiW-MC (0.04 g) under refluxing conditions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
