Abstract:
The title compds. of formula RC(OH)CONHAr are prepd. by reacting N- sulfinylamine of formula Ar-N=S=O with RC(OH)COOH in an org. solvent i.e. acetonitrile, benzene, THF., where Ar=Ph, pchlorophenyl, R=H, - COOH, -HCOH, Ph. Thus, dissolve 2-hydroxybutanoic acid (230mg) in acetonitrile (10ml), add N-sulfinylaniline (280mg) and stir for 6hr at room temp., eliminate solvent and recrystg. in water/EtOH to give N-phenyl-2-hydroxy butanamide 340mg (96%).
Abstract:
Carbonyl compounds of formula (I) are prepd. by reacting thiocarbonyl cpd. of formula (II) with tertiary alkyl thionitrate of formula (III) , in organic solvents selected from acetonitrile, tetrahydrofurane chloroform or dichloromethane, at -10-25OC. In the formulas, RP1 is alkyl, (non)substd. phenyl, alkoxy or (non) substd. phenoxy; R2 is (non)substd. aniline, sec. or tert. amine; R3 is tert. butyl, tert. pentyl or 1,1-dimethylheptyl.
Abstract:
본 발명은 무수상태의 유기 용매 하에서 하기 구조식을 갖는 테트라부틸 암모늄 퍼옥시 디술페이트 (tetra-n-butylammonium peroxydisulfate)를 이용하여 온화한 중성 상태에서 트리틸 유도체들로 보호된 히드록실기를 갖는 뉴클레오시드,뉴클레오티드 또는 t-부틸 디메틸 실릴(t-butyldimethylsilyl), 케탈(ketal) 등으로 보호된 히드록시기를 갖고 있는 알코올과 반응시켜 중성인 무수상태에서,히드록시기들의 탈보호화 반응에 관한 것이다.
