    Novel macrocycles from metal-catalyzed oxidative cyclizations of a,c-biladiene salts
    摘要:
    From the metal-promoted oxidative cyclization of several 1,19-disubstituted a,c-biladiene dihydrobromide salts, a number of novel macrocycles were prepared. For example, the cyclization of 1,-19-bis(2-(methoxycarbonyl)ethyl)-2,3,7,8,12,13,17,18-octamethyl-a,c-biladiene dihydrobromide salt (10) with copper(II) acetate afforded copper(II) 20-((methoxycarbonyl)methyl)-1-(2-(methoxycarbonyl)ethyl)-2,3,7,8,12,13,17,18-octamethyl-1,20-dihydroporphyrin (13) (39% yield), which, upon demetalation, yielded the metal-free 20-((methoxycarbonyl)methyl)-1-(2-(methoxycarbonyl)ethyl)-2,3,7,8,12,13,17,18-octamethyl-1,20-dihydroporphyrin (14) (48% yield). With the substrate 19-((ethoxycarbonyl)methyl)-1-(2-(methoxycarbonyl)ethyl)-2,3,7,8,12,13,17,18-octamethyl-a,c-biladiene dihydrobromide (15), the metal-catalyzed cyclization process produced copper(II) 20-(ethoxycarbonyl)-1-(2-(methoxycarbonyl)ethyl)-2,3,7,8,12,13,17,18-octamethyl-1,20-dihydroporphyrin (18) (27 % yield) and copper(II) 20-(ethoxycarbonyl)-2-(2-(methoxycarbonyl)ethyl)-2,7,8,12,13,17,18-heptamethyl-3-methylidene-2,3-dihydroporphyrin (23) (19 % yield). Upon demetalation of the copper dihydroporphyrin 18, 20'-(ethoxycarbonyl)-20-(2-(methoxycarbonyl)ethyl)-2,3,7,8,12,13,17,18-octamethyl-20'-homoporphyrin (28) (16.5 % yield) was isolated; demetalation of copper(II) 20-(ethoxycarbonyl)-2-(2-(methoxycarbonyl)ethyl)-2,7,8,12,13,17,18-heptamethyl-3-methylidene-2,3-dihydroporphyrin (23) yielded the free base 20-(ethoxycarbonyl)-2-(2-(methoxycarbonyl)ethyl)-2,7,8,12,13,17,18-heptamethyl-3-methylidene-2,3-dihydroporphyrin (25) (24% yield). Using chromium(III) hydroxy acetate as the oxidant (in place of copper(II)), 1,2,3,7,8,12,13,17,18-nonamethyl-1,20-dihydroporphyrin (5) (55-62%) was obtained from the 1,2,3,7,8,12,13,17,18,19-decamethyl-a,c-biladiene salt 3. Mechanisms of macrocycle formation from a,c-biladiene salts, promoted by either copper(II) or chromium(III), appear to proceed via pathways closely resembling the electrochemical cyclization reaction of 1,19-dimethyl-a,c-biladiene salts.

  • Novel peripheral substituent migration reactions in tetrapyrrole macrocycles

    c-biladiene salts bearing large terminal (1′,8′) substituents afford intermediates which suffer a variety of cleavage and cyclization reactions, in a stepwise manner, to yield mono-mesosubstituted porphyrins, chlorins, and di-meso-substituted porphyrins via facile migration reactions.

    RESEARCHERS' APPROACH The key step in the proposed pathway of the electrocyclization (Scheme 2) is the attack of a nucleophile on the angular methyl group of the cyclized intermediate 3. A similar intermediate has not hitherto been isolated from chemical cyclization. The cupric salt-catalyzed cyclization was therefore carried out on biladienes (1) that could produce corresponding intermediates (5)
    研究人员的方法 所提议的电环化途径(方案 2)中的关键步骤是亲核试剂对环化中间体 3 的角甲基的攻击。迄今为止,尚未从化学环化中分离出类似的中间体。因此,盐催化的环化反应是在可产生相应中间体 (5) 的双二烯 (1) 上进行的。但由于空间和/或电子原因,它不会发生亲核反应。研究人员的成就
