  摘要：

  在这里，我们报道了一种新的一锅法，用于从羧酸开始的SO 2 F 2介导的亲核酰基取代反应。机理研究表明，SO 2 F 2介导的酸活化是通过酸酐进行的，然后将其转化为相应的酰基氟。四丁基氯化铵或溴化物可加速酰基氟的形成。优化的卤化物加速条件可用于以30-80％的产率合成酰氟，而酯，酰胺和硫代酯的产率为72-96％，而无需对每个亲核试剂进行重新优化。

  A copper-catalysed oxidative amidation of aldehydes via N-hydroxysuccinimide ester formation is reported. The methodology employed to prepare amides directly from aldehydes has a very wide scope, is high yielding, and does not need dry conditions. This cross-coupling reaction appears to be simple and makes use of cheap, abundant and easily available reagents.

  A simple, mild, and efficient method for the conversion of primary alcohols and aldehydes to N-hydroxysuccinimide esters with (diacetoxyiodo)benzene in high yield is developed. N-Hydroxysuccinimide acts not only as an esterification partner but also as an activator of PhI(OAc)2 in this reaction.

  An efficient method to prepare amides by a cascade strategy was developed. Using nBu4NI or NaI as the catalyst and tert-butyl hydroperoxide as the oxidant, various alcohols reacted with N-hydroxysuccinimide or N-hydroxyphthalimide affording corresponding active esters in moderate to good yield. The resulting active esters were converted into amides smoothly in one pot.

  A facile method for the amidation of aldehydes by a cascade approach was developed. This methodology, reported for the first time, uses a N-heterocyclic carbene (NHC) as the catalyst, and N-hydroxysuccinimide (NHS) mediated synthesis of amides utilising TBHP as the oxidant. Various substituted aldehydes reacted smoothly with NHS giving the corresponding active esters in moderate to good yields, which

  The invention relates to a new process for preparing active esters or carboxylic acids, which consists in reacting a carboxylic acid, in the presence of an agent for binding hydrohalic acid, with a carbonate of formula: ##STR1## in which R.sup.1 denotes either a radical of formula ##STR2## in which R.sup.3 and R.sup.4, which may be identical or different, are not hydrogen atoms and denote organic radicals which may be substituted or unsubstituted and saturated or unsaturated, and may be or may not be bound to a polymer, and which can be joined together to form a hetero-cyclic system with the nitrogen atom, or a substituted or unsubstituted aryl radical which may or may not be bound to a polymer, R.sup.2 denotes a hydrogen atom, an aliphatic or cycloaliphatic radical which may be substituted or unsubstituted and saturated or unsaturated, or a substituted or unsubstituted aromatic radical, and X denotes a halogen atom. This process is especially useful for the synthesis of active esters of N-protected amino acids.
