    synthesis of highly substituted α-arylnaphthalene analogues has been developed utilizing Lewis acid-promoted regiocontrolled benzannulation of aryl(aryl‘)-2,2-dichlorocyclopropylmethanols (aryl ≠ aryl‘; abbreviated as AACMs). Both AACM diastereomers were easily prepared via highly stereoselective addition (>95/5) of ArLi to gem-dichlorocyclopropropyl aryl‘ ketones. The choice of Lewis acids determined
    利用路易斯酸促进的芳基(芳基)-2,2-二环丙基甲醇(芳基≠芳基;缩写为AACMs)的路易斯酸区域控制的苯环已开发出高取代的α-芳基类似物的有效合成方法。两种AACM非对映异构体都可以通过将ArLi高​​度立体选择性地加成(> 95/5)到宝石-dichlorocyclopropropyl aryl'ketones上来制备。路易斯酸的选择决定了本苯并环的环化区域选择性。TiCl 4和SnCl 4使用螯合途径,而甲硅烷三氟甲磺酸盐使用非螯合途径以40-91%的产率提供不对称取代的区域异构α-芳基,具有中等至出色的区域选择性(TiCl 4或SnCl 4 ; > 99 / 1-3 / 1,TBDMSOTf;> 1 / 99-1 / 4)。因此,通过选择反应顺序的顺序或合适的催化剂,可将α-芳基或α-芳基'部分(辅助芳基)引入α-芳基。证明了本方法在不对称取代的天然木脂素内酯,justicidin

    Two types of novel, sequential and regioselective Friedel-Crafts reactions of gem-dihalocyclopmpanecarbonyl chlorides with benzenes proceeded in a one-pot manner, E-3-aryl-2,2-dihalo-cyclopropanecarbonyl chlorides reacted with substituted benzenes to afford 4-aryl-3-halo- l-naphthols, while 2,2-dichlorocyclopropanecarbonyl chlorides were transformed into 4-aryl-l-naphthols in benzene or p-xylene, Both

  • Sequential and regioselective Friedel–Crafts reactions of gem-dihalogenocyclopropanecarbonyl chlorides with benzenes for the synthesis of 4-aryl-1-naphthol derivatives
    作者:Yoshinori Nishii、Yoo Tanabe
    DOI:10.1039/a605030a
    日期:——
    Novel, sequential and regioselective Friedel–Crafts type reactions of (E)-3-aryl-2,2-dihalogenocyclopropanecarbonyl chlorides 1 and 2,2-dichlorocyclopropanecarbonyl chlorides 3 with benzenes produce various 4-aryl-3-halogeno-1-naphthols 2 and 4-aryl-1-naphthols 4, respectively. One of the benzannulations involves the intramolecular cyclization of acid chlorides 1, followed by intermolecular coupling with substituted benzenes to give 4-aryl-3-halogeno-1-naphthols 2. As a demonstration of this annulation, 4-aryl-3-bromo-1-naphthols 2i and 2k are successfully converted into new analogues of 1-aryl-3-hydroxymethyl-4-methoxy-2-naphthoic acid lactones 13, a class of lignan lactones. The other benzannulation involves three series of reactions using acid chlorides 3a–c: (1) the intermolecular Friedel–Crafts acylation of 3 with one benzene molecule giving the intermediary 2,2-dichlorocyclopropyl(phenyl)methanones 14a–c; (2) the intermolecular trapping of 14a–c with another benzene molecule accompanied by regioselective ring opening; and (3) the final intramolecular cyclization giving 4-phenyl-1-naphthols 4a–c. The use of p-xylene also gives the corresponding 4-(p-xylyl)-1-naphthol 4d. The reactions of alternatively prepared ketones 14 with benzenes gives a variety of ‘unsymmetrically’ substituted 4-aryl-1-naphthols 4c,e–k under identical conditions. However, the reaction using p-methoxyphenyl ketone analogues 14g does not produce 4-aryl-1-naphthols, but gives 5-aryl-2-(p-methoxyphenyl)-3-methylfurans 16. These annulations proceed straightforwardly (in a one-pot manner) and this variation is due to the highly regioselective cyclopropane ring-openings.
    新颖的、顺序的以及区域选择性的Friedel-Crafts类反应,通过苯与(E)-3-芳基-2,2-二卤代环丙烷羧酰1和2,2-二氯环丙烷羧酰3发生反应,生成各种4-芳基-3-卤代-1-醇2和4-芳基-1-醇4。其中一类苯环增殖反应涉及酸1的分子内环化,随后与取代苯的分子间耦合,生成4-芳基-3-卤代-1-醇2。作为这一环增殖反应的示范,成功将4-芳基-3-溴-1-醇2i和2k转化为新的1-芳基-3-羟甲基-4-甲氧基-2-内酯类化合物13,这是一类木质素内酯。另一类苯环增殖反应涉及使用酸3a-c进行三系列反应:(1)与一个苯分子的分子间Friedel-Crafts酰基化反应,得到中间体2,2-二环丙基(苯基)甲酮14a-c;(2)与另一个苯分子的分子间捕捉14a-c,伴随区域选择性的开环;(3)最终的分子内环化反应生成4-苯基-1-醇4a-c。使用对二甲苯也能得到相应的4-(对二甲基基)-1-醇4d。交替制备的酮14与苯的反应在相同条件下生成多种“不对称”取代的4-芳基-1-醇4c,e-k。然而,使用对甲氧基苄基酮类化合物14g的反应并不产生4-芳基-1-醇,而是生成5-芳基-2-(对甲氧基苄基)-3-甲基呋喃16。这些环增殖反应在单锅条件下直接进行,这种变化是由于高度区域选择性的环丙烷开环反应造成的。
