A new sulfonyl fluoridereagent (E)-2-methoxyethene-1-sulfonyl fluoride (MeO-ESF) was developed and successfully applied for the construction of enaminyl sulfonyl fluoride (N-ESF). This protocol provides highly atom-economical access to diverse N-ESF and produces CH3OH as the sole byproduct under mild and environmentally benign conditions.
开发了一种新型磺酰氟试剂( E )-2-甲氧基乙烯-1-磺酰氟(MeO-ESF),并成功应用于构建烯胺基磺酰氟( N -ESF )。该协议提供了对不同N -ESF 的高度原子经济访问,并在温和和环境友好的条件下产生 CH 3 OH 作为唯一的副产品。
A Simple Protocol for the Stereoselective Construction of Enaminyl Sulfonyl Fluorides
A clickable connective hub 1-bromo-2-triazole-thane-1-sulfonyl fluoride BTESF (1) was developed and successfully applied for the fluorosulfonylvinylation of a host of primary and secondary cyclic or acyclic amines including amino acids and pharmaceuticals. Further antimicrobial experiments revealed that vinyl sulfonyl fluoride functionalized norfloxacin (3ak), ciprofloxacin (3am), and lomefloxacin (3an) exhibited 4-fold improved antimicrobial activity against Gram-positive bacteria compared to their parent drugs.
