A novel highly selective asymmetric synthesis process of 2 -fluorocyclopropylamine (Structural I). The method provided by the invention uses 1 - fluorine -1 - benzene (propylene) sulfonyl methane and chiral epichlorohydrin to construct chiral cyclopropane under basic conditions, and a new synthetic route not only achieves a special cis-trans selectivity, but also has a highly specific stereoselectivity. The synthesis route is efficient, the reaction condition is mild, the method is suitable for large industrial production in a green environment, 2 -fluorocyclopropylamine production cost is greatly reduced.

Diarylfluoromethylsulfonium salts, alternatives to freons or advanced fluorinated building blocks, are bench stable and easy-to-use sources of direct fluoromethylene (:CHF) transfer to alkenes. These salts enabled development of a trans-selective monofluorinated Johnson-Corey-Chaykovsky reaction with vinyl sulfones or vinyl sulfonamides to access synthetically challenging monofluorocyclopropane scaffolds. The described method offers rapid access to monofluorinated cyclopropane building blocks with further functionalization opportunities to deliver more complex synthetic targets diastereoselectively.

Trimethyllysine hydroxylase (TMLH) catalyses C-3 hydroxylation of Nε-trimethyllysine in the first step of carnitine biosynthesis in humans. Studies on TMLH have been hampered by the lack of established chemical methods. We report that an N
