Synthesis of Stereocontrolled Azetidine Library via Strain-Release Functionalization of 1-Azabicyclobutanes
Image source: J. Am. Chem. Soc.Introduction: Professors Benjamin F. Cravatt and Phil S. Baran developed a concise, modular, and programmable synthetic strategy based on strain-release functionalization reactions for constructing structurally complex stereopure nitrogen-containing bicyclic compounds known as Azetidine. This synthetic method allows for the parallel preparation of nitrogen-containing bicyclic compounds with defined stereostructures, which is … Read more
Goodbye Morpholine Radical
From J. Am. Chem. Soc. Hi, everyone! I wonder if you still remember that I shared an article titled 【J. Am. Chem. Soc.】Me₃N•BH₃—— Cu Catalyzed Halogenated Alkane + Primary Amide N-Alkylation, which achieved amide N-alkylation by generating alkyl radicals through XAT halogen transfer. However, in an earlier discussion, we learned that the 【J. Am. Chem. … Read more
6 Key Steps to Successfully Establish a 24/7 Internal Security Operations Center (SOC)
Hackers never sleep, so how can enterprises afford to let their defenses down? Attackers particularly favor launching attacks during non-working hours—when security personnel are fewer, significantly delaying incident response and resolution times. When retail giant Marks & Spencer faced a security incident over the Easter weekend, its e-commerce platform, which accounted for one-third of its … Read more
