Reactions of N-sulfinylfluoroalkanesulfonyl amines with nucleophiles containing reactive hydrogen
The reactions of N-sulfinylfluoroalkanesulfonyl amines, RfSO2NSO (1), with malonate or dialkyl phosphite gave 1:1 adducts RfSO2NHS(O)Nu , and with alcohols or phenols formed RfSO2NH2 and the sulfites O=S(OR)2 by double addition .Trans-sulfinylation occurred during the reaction of 1 with anilines (C6H5NH2, 4-FC6H4NH2 and C6F5NH2).
Bis(pentaluorophenyl) sulfite - A new reagent for the synthesis of activated pentafluorophenyl esters of N-protected amino acids
A method was proposed for the preparation of bis(perfluorophenyl) sulfite, an effective new reagent for the synthesis of pentafluorophenyl esters of N-protected amino acids without racemization.
