“The media will always have axes to grind but the police have the capacity to project their side of the story better” – Neeraj Kumar
No full textNeeraj Kumar recently retired as the Commissioner of Police Delhi, having served in the Indian Police Service for over 37 years in a wide range of roles. He has now penned his first book, a collection of stories pertaining to high-profile cases solved during his nine year tenure at the Central Bureau of Investigation. Ahead of the London launch of the book, he spoke to Sonali Campion about the IPS, security and corruption in India. Dial D for Don: Inside stories of CBI missions will be launched at the Nehru Centre on 13 July at 6.30pm. The event is free and open to all and will include a panel with leading journalist Owen Bennett Jones and the author. Details here

Electrocatalytic Formal C(sp2)–H Alkylations via Nickel‐Catalyzed Cross‐Electrophile Coupling with Versatile Arylsulfonium Salts
No full textProducing sp3‐hybridized carbon‐enriched molecules is of particular interest due to their high success rate in clinical trials. The installation of aliphatic chains onto aromatic scaffolds was accomplished by nickel‐catalyzed C(sp2)–C(sp3) cross‐electrophile coupling with arylsulfonium salts. Thus, simple non‐prefunctionalized arenes could be alkylated through the formation of aryldibenzothiophenium salts. The reaction employs an electrochemical approach to avoid potentially hazardous chemical redox agents, and importantly, the one‐pot alkylation proved also viable, highlighting the robustness of our approach

Weak-coordination-auxiliary aminocatalysis enables directed [3 + 2] cyclization for 2-acylindolizines
No full textA weak-coordination-auxiliary amino-catalyzed approach enables directed [3 + 2] cyclization of α,β-unsaturated ketones and N-heteroaryl ketones for the desired 2-acylindolizines
via
an iminium ion/enamine tandem sequence.The synthesis of 2-acylindolizines, possessing a readily modifiable ketone group, is of significant importance as it provides versatile precursors for the preparation of various indolizines. However, due to the electronically less active and more sterically demanding nature of α,β-unsaturated ketones toward iminium formation with an aminocatalyst, the efficient one-pot transformation of α,β-unsaturated ketones for distinct 2-acylindolizines bearing sensitive groups represents a challenge for synthetic chemists. Herein, we report a weak-coordination-auxiliary amino-catalyzed approach that enables directed [3 + 2] cyclization of α,β-unsaturated ketones and N-heteroaryl ketones for the desired 2-acylindolizines
via
an iminium ion/enamine tandem sequence. A highly broad range of commercially available α,β-unsaturated ketones (internal, terminal, and cyclic enones) can act as coupling partners for readily accessible 2-acylindolizines relative to the existing state-of-the-art methods. Control experiments and in-depth DFT calculations highlight the importance of weakly coordinated glycine's carboxylic group in promoting the intramolecular cyclization and 1,5-proton transfer processes.A weak-coordination-auxiliary amino-catalyzed approach enables directed [3 + 2] cyclization of α,β-unsaturated ketones and N-heteroaryl ketones for the desired 2-acylindolizines

A Cost- and Energy-Efficient Sram Design Based on a New 5 I-P Majority Gate in Qca Nanotechnology
No full textMisra, Neeraj Kumar/0000-0002-7907-0276; Ahmadpour, Seyed-Sajad/0000-0003-2462-8030Quantum-dot Cellular Automata (QCA) is a revolutionary paradigm in the Nano-scale VLSI market with the potential to replace the traditional Complementary Metal Oxide Semiconductor system. To demonstrate its usefulness, this article provides a QCA-based innovation structure comprising a 5-input (i-p) Majority Gate, which is one of the basic gates in QCA, and a Static Random Access Memory (SRAM) cell with set and reset functionalities. The suggested design, with nominal clock zones, provides a reliable, compact, efficient, and durable configuration that helps achieve the optimal size and latency while decreasing power consumption. Based on the suggested 5 i-p majority gate, the realized SRAM architecture improves energy dissipation by 33.95 %, cell count by 31.34 %, and area by 33.33 % when compared to the most recent design designs. Both the time and the cost have been decreased by 30 % and 53.95 %, respectively
