  Base-promoted reaction of O-sulfonylated hydroxamic acids with nucleophiles. A new method for the synthesis of .alpha.-substituted amides

  摘要：

  Treatment of a series of hydroxamic acids 2 with mesyl chloride in the presence of 2 equiv of triethylamine at 0-degrees-C gives 2-chloroamides 3 in good yields. Use of a single equivalent of triethylamine gives the (N-mesyl-oxy)amides 1, which are versatile synthetic intermediates as they can be readily converted to 2-bromoamides 4 with lithium bromide and triethylamine and to 2-hydroxyamides 5 with triethylamine in aqueous acetonitrile.

  Effective new syntheses of 2-azido amides and 2-amino amides from N-(mesyloxy) amides 1 have been developed. 2-Azido amides are produced by treating 1 with sodium azide in the presence of 15-crown-5. 2-Amino amides result from the reaction of 1 with various amines. Regiochemical control in the preparation of 2-amino amides is possible by modulating the amine nucleophilicity by steric bulk.
