  Thermolyses of α-phosphorylmethyl tetrazolyl sulfoxides in the presence of 2,3-dimethyl-1,3-butadiene and their reactions with several amines

  摘要：

  We have synthesized alpha-(phosphoryl)methyl tetrazolyl sulfoxides and examined the reactivities in the thermolyses and in the presence of several amines, such as aniline, benzylamine, piperidine, pyrrolidine, and morpholine. Thermolyses of the derivatives in the presence of 2,3-dimethyl-1,3-butadiene afforded 2-phosphoryl substituted 4,5-dimethyl-3,6-dihydro-2H-thiopyran S-oxide. In addition, novel phosphinecar-bothioamides were obtained in the reaction of the derivatives with amines. (c) 2008 Elsevier Ltd. All rights reserved.

  coupling reaction of thioamides has been developed to provide 1,3-benzothiazine derivatives in good yields. The reaction proceeds smoothly to reach completion at room temperature within 1 min under metal-free conditions. This protocol provides a mild and efficient strategy for the synthesis of six-membered N,S-containing heterocycles. Preliminary mechanistic studies indicate that a spirocyclic intermediate
