  A straightforward synthesis and structure of unprecedented iminium salts of dihydropyrido[3,2-e][1,3]thiazines

  摘要：

  Unprecedented 2-iminium chloride salts of 5,8-dihydro-2H-pyrido[3,2-e][1,3]thiazines derivatives (8) were easily synthesized in one step from the corresponding o-chloroformyl-1,4-dihydropyridime (2) and thiourea. The Structural Study has been carried out by X-ray crystallography and theoretical calculations at the B3LYP/6-31G* levels and reveal that the new salts exhibit appropriate structural features to behave as calcium channel modulators.

  摘要：

  在没有溶剂的情况下，在微波辐射下，在乙酸铵的存在下，由Meldrum的酸，乙酰乙酸甲酯和适当的苯甲醛通过一锅缩合反应制得了4-芳基取代的5-烷氧基羰基-6-甲基-3,4-二氢吡啶酮。这种快速方法主要由于在相同条件下进行常规加热而产生的特定非热微波效应（17-28％），从而可以高产率（81-91％）生产纯净产品。

  Here we describe the efficient synthesis of alkyl 4-arylsubstituted-6-chloro-5-formyl-2-methyl-1,4-dihydropyridine-3-carboxylates and 4-arylsubstituted-4,7-dihydro-furo[3,4-b]pyridine-2,5(1H,3H)-diones via microwave-accelerated reaction of alkyl 4-arylsubstituted-2-methyl-6-oxo-1,4,5,6-tetrahydro-3-pyridinecarboxylates with the appropriate reagents. This eco-friendly approach to these valuable dihydropyridine derivatives does not involve the harsh or highly contaminating conditions common in classical heating and offers a reduction or even elimination of solvent use and recovery, simplification of the work-up procedures, facility of scale up, and low energy consumption, in addition to moderate to higher yields.

  Novel methyl 4,7-dihydro-1H-pyrazolo[3,4-b]pyridine-5 3a-e have been prepared in a two step procedure from the readily available 2-oxo-1,2,3,4-tetrahydropyridine-5-carboxylates 1a-e by treatment with the Vilsmeier-Haack reagent. Further treatment of the novel o-chloroformyl substituted methyl 1,4-dihydropyridine-5-carboxylates 2a-e with hydrazine affords the corresponding methyl pyrazolo[3,4-b]pyridine-5-carboxylates in good yields. Semiempirical calculations reveal a favoured geometry with a boat conformation in the dihydropyridine system and a planar pyrazole ring.
