  MICROWAVE-ASSISTED RAPID HYDROLYSIS AND PREPARATION OF THIOAMIDES BY WILLGERODT-KINDLER REACTION

  摘要：

  Aldehydes and aryl alkyl ketones were efficiently transformed to thioamides with the same number of carbon atoms via Willgerodt-Kindler reaction under microwave irradiation in solvent-free conditions. The thioamides obtained were hydrolyzed to corresponding carboxylic acids with microwave dielectric heating in one minute. Both reactions are very fast and the yields are excellent.

  ABSTRACT A mixed bases mediated protocol is developed to synthesize thioamides from N-aryl or N-alkylamide, aldehyde and elemental sulfur in water. This reaction requires no addition of external oxidant and avoids large excess of amides. Various functional groups and pharmaceutically interesting heteroaromatic rings could be introduced via this efficient procedure. GRAPHICAL ABSTRACT

  Three component reactions of olefins, amines, and sulfur were studied. Thioamidation of styrenes is base-controlled, and 2-phenylethanethioamides and benzothioamides were obtained selectively in the presence of two different bases. This protocol offers a simple and efficient procedure for the synthesis of thioamides.

  A metal-free CC bond cleavage reaction of β-nitrostyrenes in the presence of elemental sulfur and secondary amines/amides is described. Elemental sulfur serves as both a raw material and an oxidant for CC bond cleavage, and secondary amines or amides are both feasible nitrogen sources. Besides mild reaction condition and simple work-up procedure, the method provided thioamides with good to excellent

  transition-metal-free cleavage reaction of C–C triple bonds in aromatic alkynes with S8 and amides furnishes aryl thioamides in moderate to excellent yields. The remarkable features of this thioamidation include the metal-free cleavage of C–C triple bond, mild reaction conditions, as well as wide substrate scope that is particularly compatible with some internal aromatic alkynes and acetamides.

  Thioamides, readily available from aldehydes, sulfur and secondary amines, can be converted to unsymmetrical ketones by the carbophilic addition of organolithiums to the thiocarbonyl group. Reduction of the intermediates with lithium aluminum hydride gives α-alkylated or α-arylated amines.

  硫酰胺很容易从醛，硫和仲胺中获得，可以通过将有机锂的碳亲碳加成到硫代羰基上，将硫酰胺转化为不对称的酮。用氢化锂铝还原中间体得到α-烷基化或α-芳基化的胺。
