  Studies on organophosphorus compounds XXI. the dimer of p-methoxyphenylthionophosphine sulfide as thiation reagent. a new route to thiocarboxamides

  摘要：

  AbstractThe thiation properties of the dimer of p‐methoxyphenylthionophosphine sulfide, 1, has been investigated by performing reactions with a representative series of aliphatic and aromatic primary, secondary, and tertiary carboxamides in the temperature range 80‐100 °C using HMPA as solvent. This new method seems to be superior to all others as in most cases quantitative yields are found. Salicylanilide, when reacted with 1, in HMPA, yields salicylthioanilide and a new type of phosphorus heterocycle, 3, whose structure has been determined by NMR‐and X‐ray analyses. 13C NMR data are tabulated for a series of thioamide carbons.

  日期：2016.1.15

  An efficient aqueous synthesis of thioamides through aldehydes, sodium sulfide, and N-substituted formamides has been developed. Both alkyl and aryl aldehydes are amenable to this protocol. N-Substituted formamides are essential for this transformation. Readily available inorganic salt (sodium sulfide) serves as the sulfur source in water, which makes this method much more practical and efficient.

  已经开发了通过醛，硫化钠和N-取代的甲酰胺的硫酰胺的有效的水性合成。烷基醛和芳基醛均适用于该方案。N-取代的甲酰胺对于该转化是必不可少的。现成的无机盐（硫化钠）是水中的硫源，这使该方法更加实用和有效。此外，已经建立了通过该方案对生物活性分子和衍生物进行后期修饰的方法。

  An efficient decarboxylative thioamidation of arylacetic and cinnamic acids has been developed employing formamides as amine surrogate and sulfur as promoter. Thioamides with variant structural features are obtained under mild reaction conditions without the use of transition metal catalysts and oxidants.

  A mild, greener approach toward thioamide synthesis has been developed. Its unique features include water-mediated reaction with no input energy, additives, or catalysts as well. The presented protocol is attractive with readily available starting materials and the use of different array amines, along with a scaled-up method.

  作者：Yongjun Bian、Xingyu Qu、Yongqiang Chen、Jun Li、Leng Liu

  DOI：10.3390/molecules23092225

  日期：——

  Thiourea as a sulfur atom transfer reagent was applied for the synthesis of aryl thioamides through a three-component coupling reaction with aryl aldehydes and N,N-dimethylformamide (DMF) or N,N-dimethylacetamide (DMAC). The reaction could tolerate various functional groups and gave moderate to good yields of desired products under the transition-metal-free condition.
