    The synthesis of a series of enantiomerically pure, C2-symmetric 4,4′,5,5′-tetrahydro-2,2′-methylenebis[oxazoles] and 4,4′,5,5′-tetrahydro-2,2′-bi(oxazoles) is reported. Copper complexes with anionic tetrahydromethylenebis[oxazole] ligands are efficient catalysts for the enantioselective cyclopropane formation from olefins and diazo compounds (up to 96% ee in the reaction of styrene with menthyl diazoacetate)

    DOI:10.1055/s-1986-31607

    Convenient two step procedures for the synthesis of 2,2′-biimidazole (3)and its dihydrochloride salt (4) starting with bis-methylimidate (1) in an overall yield of 72 and 83%, respectively, are reported. Bis-methylimidate(1) was treated with two equivalents of aminoacetaldehyde dimethyl acetal underacid-catalyzed conditions to provide bis-N-(2,2-dimethoxyethylacetamidine)dihydrochioride (2) in 84% yield. Fusion of 2 with an equivalent of p toluenesulfonic acid at 200°C gave 3 in 86% yield. Alternatively, 2 was refluxed with 5 molar hydrochloric acid to provide 4 as well as 3 in combined yield of 99%. Evidence is presented for the intermediacy of 2-[4(5)-methoxy-2-imidazolyl]imidazole (5) in the formation of the title compound. Water-soluble 4 is converted to 3 by treatment with potassium carbonate.

Rate constants of the tautomerism of OA7 dissolved in methylcycloherane-d 14 (MCY) and in acetonitrile d 3 (AN) could be obtained, including the full kinetic HH/HD/DD isotope effects
    已通过动态核磁共振光谱研究了由氮原子之间的分子内简并双质子转移组成的奥拉脒的互变异构现象。对两种双环口服脒进行了实验,即 2,2'-双(3,4,5,6-四氢-1,3-二嗪)(OA6)和 2,2'-双(4,5,6,7-四氢-1,3-二氮杂) (OA7) 溶于有机溶剂。为此,两种化合物都必须用 15 N 和部分用 2 H 标记。与 OA7 的情况相比,OA6 的互变异构太慢而无法通过 NMR 检测到。可以获得溶解在甲基环醚-d 14 (MCY) 和乙腈 d 3 (AN) 中的 OA7 互变异构的速率常数,包括完整的动力学 HH/HD/DD 同位素效应
