  Synthesis of 7H-Thiopyrano[2,3-d]pyrimidines by Hydrobromic Acid-Mediated Cyclization of 1-[4-(1,1-Dimethylethylsulfanyl)pyrimidin-5-yl]prop-2-en-1-ols

  摘要：

  7-Aryl- or 5,7-diaryl-4-methoxy-2-methylsulfanyl-7H-thiopyrano[2,3-d]pyrimidines have been prepared in satisfactory overall yields starting from 4-chloro-6-methoxy-2-(methylsulfanyl)pyrimidine by a facile three-step sequence. 4-Chloro-5-lithio-6-methoxy-2-(methylsulfanyl)pyrimidine was generated by the treatment of 4-chloro-6-methoxy-2-(methylsulfanyl)pyrimidine with LDA and was allowed to react with 3-arylprop-2-enals (cinnamaldehyde and its derivatives) or 1,3-diarylprop-2-en-1-ones (chalcone and its derivatives) to give the corresponding 3-aryl- or 1,3-diaryl-1-(4-chloropyrimidin-5-yl)prop-2-en-1-ol derivatives, respectively. Substitution of the 4-chloro group with sodium 1,1-dimethylethylthiolate gave 3-aryl- or 1,3-diaryl-1-[4-(1,1-dimethylethylsulfanyl)pyrimidin-5-yl]prop-2-en-1-ol derivatives, of which treatment with an equivalent of hydrobromic acid provided the desired products.

  The first Fe-facilitated decarboxylative cross-coupling reaction between α-oxocarboxylic acids and acrylic acids in aqueous solution has been developed. This transformation is characterized by its wide substrate scope and good functional group compatibility utilizing inexpensive and easily accessible reagents, thus providing an efficient and expeditious approach to an important class of α,β-unsaturated

  2,4-Diaryl-1,1,1-trifluorobut-3-en-2-oles and their TMS-ethers in H2SO4 at room temperature in just 2 min are quantitatively cyclized into 1-aryl-3-trifluoromethyl-1H-indenes. The reaction proceeds through an intermediate formation of the corresponding CF3-allyl cations, which are cyclized regioselectively at the allyl carbon atom most remote from the CF3-group. The obtained CF3-indenes in solution
