  Efficient Synthesis of Pyrimido[1,2-c] [1,3]benzothiazin-6-imines and Related Tricyclic Heterocycles by S_NAr-Type C−S, C−N, or C−O Bond Formation with Heterocumulenes

  摘要：

  A simple and practical synthetic method of pyrimido[1,2-c]-[1,3]benzothiazin-6-imines and related tricyclic heterocycles has been developed. Treatment of 2-(2-haloaryl)-tetrahydropyrimidines with NaH and a heterocumulene such as carbon disulfide, isothiocyanates, and isocyanates in DMF provides the desired cyclization products through a regioselective SNAr-type reaction. This method provides direct access to PD 404182 and related compounds.
