An efficient oxidative chlorination of thiols to Nα-protected amino alkyl sulfonyl azides is delineated. The reaction involves in situ generation of sulfonyl chloride employing Nchlorosuccinimide and tetrabutylammonium chloride-water in acetonitrile, followed by the reaction with sodium azide. The protocol is simple, straight forward, mild and high yielding. Amino acids with simple as well as bifunctional
描绘了将硫醇有效氧化氯化为Nα-保护的氨基烷基磺酰基叠氮化物的方法。该反应包括使用NHC琥珀酰亚胺和四丁基氯化铵-水在乙腈中原位产生磺酰氯,然后与叠氮化钠反应。该方案简单,直接,温和且产率高。具有简单以及双官能侧链的氨基酸用于获得Nα-保护的氨基烷基磺酰基叠氮化物。此外,磺酰叠氮化物被用于通过Cu(OAc)2 .H 2 O / 2-氨基苯酚与丙酸催化的点击反应来合成非天然氨基酸。
