Chemistry Departmental Lecture Series brings another captivating webinar on “Organocatalysis Using N-Heterocyclic Carbenes (NHCs)”. Dr A T Biju, Associate Professor, Department of Organic Chemistry, Indian Institute of Science, Bengaluru, will deliver the keynote address on Saturday, September 04, 2021, at 11 am.
Catalysis is a fundamentally sustainable process, which can be used to produce a wide range of chemicals and their intermediates. Among the various catalytic methods, N-heterocyclic carbene (NHC)-catalyzed umpolung of aldehydes is widely used for unconventional access to target molecules. Moreover, NHC-catalysis is known for umpolung of Michael acceptors, but imine umpolung was unknown in this realm of catalysis. In this context, Dr Biju and his team have demonstrated, for the first time, the NHC-catalyzed umpolung of imines for the synthesis of 2,3-disubstituted indoles, functionalized quinolines and dihydroquinoxalines. In addition, NHC-catalysis is widely used for the generation of α,β-unsaturated acylazoliums, followed by their interception with various nucleophiles, the formal [3+3] annulation reactions. In this area, recently Dr Biju and his team have reported the enantioselective NHC-catalyzed annulation reactions for the synthesis of dihydropyranones, dihydropyridinones, cyclopentenes, pyrazoles, spirocyclohexadienones, tricyclic δ-lactones, tetracyclic indoles etc., where NHC-bound α,β-unsaturated acylazoliums are the key intermediates. Very recently, Dr Biju employed the umpolung of aldehydes for the synthesis of axially chiral C-N bond-containing molecules. The keynote address will shed further light on this.
Dr A T Biju received his M Sc from Sacred Heart College Thevara (affiliated to MG University, Kerala, India) and PhD from CSIR-NIIST (Formerly RRL), Trivandrum, India. After that, he worked as a post-doctoral fellow with Prof. Tien-Yau Luh at the National Taiwan University, Taipei. He has also worked as an Alexander von Humboldt fellow with Prof. Frank Glorius at the Westfälische Wilhelms-Universität Münster, Germany. In June 2011, he began his independent research career at the CSIR-National Chemical Laboratory, Pune. He became an Associate Professor at the Department of Organic Chemistry, Indian Institute of Science, Bengaluru, in June 2017. His research focuses on the development of transition-metal-free carbon-carbon and carbon-heteroatom bond-forming reactions using aryne chemistry and N-heterocyclic carbene (NHC) organocatalysis and their application in organic synthesis.
Chemistry enthusiasts are welcomed to avail the opportunity to listen to him on Saturday, September 04, 2021, at 11 am. Register now.
The Department of Chemistry is organising the second episode of the Department Lecture Series on August 28, 2021, at 03.00 pm. Dr Rajendra Joshi, Chairman of RI Group, will deliver a lecture on the topic “Cost-effective high-end research instrumentation and materials in India”.
Indigenous development of upper end scientific analytical instruments in India has always been a big challenge. RI Instruments & Innovation India has proved that with cohesive teamwork, this is very much possible. The group has designed Raman Spectrometer, RIUS (Universal Spectroscopy), RIMS (Modular spectroscopic work station) XRD, TEM (Under Trial), Class AAA Solar simulator, the world’s smallest USB microscope and a few more.
About the speaker:
Dr Rajendra Joshi is the recipient of the National Innovation Award for the year 2019 by the Ministry of Chemicals and Fertilizer, Govt. of India for the innovation of Graphene Oxide / Li based rechargeable batteries with replaceable electrodes. As an Instrumentation Professional and Material’s Physicist, he started his career at National Physical Laboratory, New Delhi in the year 1997 – 1998. He has certification in Quality Control/R&D Professional training from Japan, Germany, France, Italy and UK. Cost-effective solar simulator, Indian designed drone for societal applications, Graphene Oxide-based rechargeable battery with replaceable electrodes etc are some of his major achievements.
