  • Novel Synthesis of α-Acetylstyrylphosphonates
    作者:Ryozo Sakoda、Hiroo Matsumoto、Kiyotomo Seto
    DOI:10.1055/s-1993-25926
    日期:——
    α-Acetylstyrylphosphonates were conveniently synthesized from 2-oxopropylphosphonates and substituted (dimorpholinomethyl)-benzenes (aminals). 4-Benzylidenemorpholinium carboxylates, generated from aminals by the action of α-halo acids, reacted with the phosphonates to give the products by elimination of the amine. The yields were influenced by the nature of substituents and their position in the phenyl ring and could be improved by adjustment of the acidities of the reacted acids. α-Acetylstyrylphosphonates containing various substituents on every position (at the 2-, 3-, or 4-position) in the phenyl ring were obtained generally in excellent yields using monochloroacetic acid.
    α-Acetylstyryl磷酸酯可以通过2-氧代丙基磷酸酯和取代的(二吗啉甲基)苯(氨基缩醛)方便地合成。在α-卤代酸的作用下,从氨基缩醛生成的4-苄叉吗啉鎓羧酸酯与磷酸酯反应,通过消除胺得到产物。产率受取代基的性质及其在苯环中的位置影响,并且可以通过调整反应酸的酸度来提高。使用单氯乙酸,通常可以以优异的产率获得在苯环的2-、3-或4-位置上含有各种取代基的α-Acetylstyryl磷酸酯。
  • Improved synthesis of methyl 2,6-dimethyl-4-(2-nitrophenyl)-5-(2-oxo-1,3,2-dioxaphosphorinan-2-yl)-1,4-dihydropyridine-3-carboxylate (DHP-218).

    DOI:10.1248/cpb.36.1139

    Attempts were made to improve the synthesis of methyl 2, 6-dimethyl-4-(2-nitrophenyl)-5-(2-oxo-1, 3, 2-dioxaphosphorinan-2-yl)-1, 4-dihydropyridine-3-carboxylate (DHP-218), a new calcium antagonist. 2-Acetonyl-2-oxo-1, 3, 2-dioxaphosphosphorinane (5a), the key intermediate, was prepared from the allenylphosphonate (2) via the enaminophosphonate (4) in a good yield. Subsequently, the Knoevenagel condensation using 5a and the imine (6a) gave the benzylideneacetonylphosphonate (7a) in a good yield without the use of the Horner-Emons reaction. This condensation also gave good results for other acetonylphopshonates. The final step gave DHP-218 in a good yield through a modified Hantzsch synthesis with the use of a dehydrating agent. The overall yield was increased from 1.7% to 22%.
    尝试改进甲基2,6-二甲基-4-(2-硝基苯基)-5-(2-氧代-1,3,2-二氧杂磷-2-基)-1,4-二氢吡啶-3的合成-羧酸盐(DHP-218),一种新型钙拮抗剂。关键中间体2-丙酮基-2-氧代-1,3,2-二氧杂磷膦烷(5a)是由丙二烯基膦酸酯(2)经由烯氨基膦酸酯(4)以良好的收率制备的。随后,使用5a和亚胺(6a)进行Knoevenagel缩合,在不使用Horner-Emons反应的情况下以良好的收率得到亚苄基丙酮基膦酸酯(7a)。这种缩合对于其他乙酰基磷酸酯也给出了良好的结果。最后一步通过使用脱水剂的改进的 Hantzsch 合成以良好的收率得到了 DHP-218。总收益率从1.7%提高到22%。

    A series of 1, 4-dihydropyridine-5-cyclic phosphonate derivatives, designed as analogues of 1, 4- dihydropyridine-3, 5-dicarboxylate calcium antagonists, was synthesized and examined for antihypertensive activity. Several compounds were proved to have activities superior or comparable to that of nifedipine in lowering blood pressure in normotensive and spontaneously hypertensive rats (SHR). Among these compounds, methyl 2, 6-dimethyl-5- (2-oxo-1, 3, 2-dioxaphosphorinan-2-yl) -4- (2-nitrophenyl) -1, 4-dihydropyridine-3-carboxylate (31, DHP-218) was approximately 7 times more active than nifedipine in SHR and was selected for further development and clinical evaluation. The structure-activity relationships are discussed.
