Early warning is triggered during index updating, the updating timeliness and reliability of early warning data can be improved, meanwhile, the situation that when an early warning engine is executed, early warning is invalid due to index data missing is avoided, human resource waste is reduced, and an early warning mechanism is improved. In addition, the invention also relates to a blockchain technology, and the early warning rule configuration table can be stored in the blockchain.

Novel asymmetric catalytic nucleophilic fluorine heterocyclization reaction system and application thereof in chiral non-natural amino acid module synthesis

The invention discloses a novel asymmetric catalytic fluorine heterocyclization reaction system and application thereof. The novel asymmetric catalytic fluorine heterocyclization reaction system provided by the invention comprises a chiral iodine catalyst and etherified boron trifluoride, and is applied to a catalytic asymmetric nucleophilic fluorine heterocyclization reaction of unsaturated amide; a fluoro oxazine derivative is obtained through treatment after the reaction; and the obtained fluoro oxazine derivative is subjected to hydrolysis and oxidation reaction to obtain the chiral non-natural amino acid. The reaction system provided by the invention has the following advantages: etherified boron trifluoride is used as a fluorine reagent, is cheap and easy to obtain, and has good stability and low toxicity; the reaction conditions are mild; the chiral iodine catalyst is simple to prepare and does not need a complex ligand; the system is environment-friendly and free of heavy metal pollution and precious metal waste; the obtained product is a fluoro oxazine derivative active molecular structure unit with two chiral centers; chiral non-natural amino acid can be obtained through conversion reaction of the product; and the chemical selectivity and stereoselectivity of the reaction are good, and the yield and optical purity are high.
