  Substituted glycidic acid esters, of the formula <;FORM:0372013/IV/1>; where R1 is hydrogen or alkyl, R2 is a cyclic residue when R1 is hydrogen or any organic residue when R1 is alkyl, and X represents a saturated chain, are manufactured by condensing a halogen-acetic acid ester with a cyclic aldehyde or with a ketone in which the carbon atom of the oxo-group is bound to alkyl and to any organic residue or is a member of a saturated ring, by means of an alkali metal, an alkali metal amide or an alkali metal alcoholate, in a medium in which during the condensation process alkali metal halide does not separate on the condensing agent, viz. a liquid hydrocarbon or a liquid halogenated hydrocarbon. The products are converted into substituted acetaldehydes by saponifying with an alkali, acidifying the solution and steam distilling. In examples: (1) benzaldehyde is condensed with chloracetic acid ethyl ester by means of sodium in the presence of xylene yielding phenylglycidic acid ethyl ester, which is converted into phenylacetaldehyde; (2) 4-methoxybenzaldehyde is similarly treated; (3) 4-chlorobenzaldehyde is similarly converted into 4-chlorophenylglycidic acid ethyl ester and 4-chlorophenylacetaldehyde; (4) acetophenone is condensed with chloracetic acid ethyl ester by means of sodium amide in the presence of benzene or xylene, producing b -phenyl-b -methylglycidic acid ethyl ester, which is converted into 1-oxo-2-phenyl-2-methylethane (hydratropa aldehyde); (5) 2-oxo-6 : 10-dimethylundecane (hexahydropseudoionone) and chloracetic acid ethyl ester are condensed by means of sodium in xylene, yielding the corresponding glycidic ester, which is transformed into 1-oxo-2 : 6 : 10-trimethylundecane; (6) decahydro-2-oxonaphthalene (b -decalone) similarly yields the corresponding glycidic acid ester which is converted into decahydro-2-naphthaldehyde; (7) 1 : 1 : 3-trimethyl-2- (23 - oxobutyl)-cyclohexane (tetrahydroionone) is similarly condensed to produce the corresponding glycidic acid ester, which is converted into 1 : 1 : 3-trimethyl-2-(2<;4>; - oxo - 2<;3>; - methobutyl) - cyclohexane. The properties are also given of the substituted glycidic acid esters and substituted acetaldehydes obtained from: 4-methyl- and 4-ethyl-benzaldehyde, 2 : 4-dimethylbenzaldehyde, 4-isopropylbenzaldehyde, 4-(1<;1>;-methopropyl)-benzaldehyde (obtainable by the action of carbon monoxide on 2-phenylbutane in the presence of aluminium chloride), 2 : 4-diisopropylbenzaldehyde, 5 : 6 : 7 : 8-tetrahydro-1-naphthaldehyde (obtainable by the action of carbon monoxide on tetrahydronaphthalene in the presence of aluminium chloride); 2-oxodecane (methyloctylketone), 2-oxoundecane (methylnonylketone), 2-oxo-2-(p-isopropylphenyl)-ethane (p-isopropylacetophenone), 2-oxo-2-(p-methoxyphenyl)-ethane (methyl - p - methoxyphenylketone), 2 - oxo - 4-phenylbutane, 2 - oxo- 4 - (p-isopropylphenyl)-butane, and 1 : 1 : 3-trimethyl-2-(2<;3>;-oxopentyl)-cyclohexane (obtainable by hydrogenating the corresponding a -methylionone). Other starting materials specified are naphthaldehyde and furfural on the one hand and bromacetic acid esters on the other.

  A new reaction of aryl 2,3-epoxy esters with 2-aminopyridines has been developed that involves multiple C–O/C–N bond-breaking/formation reactions in one chemical step. Compared with known reactions of α,β-epoxy esters, which take place through oxiranyl C–O or C–C bond cleavage, the present reaction exploits the tendency of the oxirane ring to act as a bi-electrophile. Thus, the reaction follows a unique

  已开发出一种芳基 2,3-环氧酯与 2-氨基吡啶的新反应，该反应在一个化学步骤中涉及多个 C-O/C-N 键断裂/形成反应。与通过环氧乙烷基 C-O 或 C-C 键断裂发生的 α,β-环氧酯的已知反应相比，本反应利用了环氧乙烷环作为双亲电试剂的趋势。因此，该反应遵循独特的环氧化物 C-O 键裂解、α-烯胺酯形成和具有化学选择性、区域选择性和非对映选择性的分子内转酰胺的级联途径。该反应允许获得生物学相关的 (Z)-2-亚甲基咪唑并[1,2-a]pyridin-3-ones。水和乙醇是唯一的副产品。该反应是灵活的，芳基 2,3-环氧酯以及具有给电子或吸电子官能团的 2-氨基吡啶，可以使用。与各种布朗斯台德酸和路易斯酸催化剂不同，多磷酸在这种分子间级联反应中起着多功能作用。

  the first time. 2-Arylideneimidazo[1,2-a]pyridinones as potential topoisomerase IIα (hTopoIIα)-targeting anticancer compounds were considered. A multifunctional activator, polyphosphoric acid, enabled to realize a cascade reaction of 2-aminopyridine with 2,3-epoxyesters toward synthesis of 2-arylideneimidazo[1,2-a]pyridinones. Most of the compounds exhibited hTopoIIα-selective poison activity with efficiency

  首次研究了生物活性天然产物金黄色素的脚手架跳跃。有人考虑将2-Arylideneimidazo [1,2- a ]吡啶酮作为潜在的拓扑异构酶IIα（hTopoIIα）靶向抗癌化合物。多功能活化剂多磷酸能够实现2-氨基吡啶与2,3-环氧酯的级联反应，从而合成2-芳基亚氨基咪唑[1,2- a]]吡啶酮。大多数化合物表现出hTopoIIα选择性毒性活性，其效率高于依托泊苷和DNA结合特性，但不与hTopo I相互作用。这些化合物在纳摩尔浓度范围内表现出明显的抗增殖活性，对正常细胞的毒性相对较弱，抑制了侵袭性，并且凋亡作用。还观察到抑制微管蛋白装配的活性CDK1和pCDK1。有趣的是，与具有相同取代作用的相应母体金黄色素相比，具有代表性的强效化合物的hTopoIIα抑制作用（体外和离体研究）和抗增殖活性更高，表明这种支架跳跃策略在药物化学研究中的重要性。
