  • Lithiation of five-membered heteroaromatic compounds. The methyl substituted 1,2-azoles, oxadiazoles, and thiadiazoles
    作者:R. G. Micetich
    DOI:10.1139/v70-334
    日期:1970.7.1

    The lithiation of various methyl substituted isoxazoles, isothiazoles, pyrazoles, oxadiazoles, and thiadiazoles using n-butyllithium has been studied. Three types of reactions, namely, lateral lithiation, ring cleavage, and addition of butyllithium to the ring, have been found. 3,5-Dimethylisoxazole, 3-phenyl-5-methylisoxazole, 3,4-dimethyl-1,2,5-oxadiazole, 2,5-dimethyl-1,3,4-thiadiazole, 3-phenyl-5-methyl-1,2,4-oxadiazole, and 3,5-dimethyl-1,2,4-thiadiazole all undergo lateral lithiation to give the respective acetic acids after carboxylation. 1-Methyl-3,5-disubstituted pyrazoles form the 1-lithiomethyl derivatives, while 1-phenyl-3,5-disubstituted pyrazoles are converted to the 1-ortholithiophenyl-3,5-disubstituted pyrazoles. 4-Methylisothiazole is lithiated mainly at C-5, but also suffers ring cleavage to form 1-n-butylthio-2-cyanoprop-1-ene. Heteroaromatic compounds containing an N—S bond, such as 3,4-dimeth yl-1,2,5-thiadiazole, 4-methyl-5-phenyl-1,2,3-thiadiazole, and 3,5-dimethylisothiazole, undergo nucleophilic attack at sulfur with resulting ring cleavage. 3,5-Dimethylisothiazole produces 2-n-butylthiopent-2-en-4-one. 3-Methyl-5-phenyl-1,2,4-oxadiazole gave 3-methyl-5-phenyl-5-n-butyl-1,2,4-dihydroöxadiazole by addition to the azomethine bond. The results of these lithiations are discussed. 3-Methyl-5-lithiomethylisoxazole was converted to various derivatives. Nuclear magnetic resonance spectral analysis was used to establish the identity of the products.

    各种甲基取代异噁唑、异唑、吡唑、噁二唑和噻二唑化反应已经被研究。发现了三种类型的反应,即侧链化、环裂解和丁基加入环中。3,5-二甲基异噁唑、3-苯基-5-甲基异噁唑3,4-二甲基-1,2,5-噁二唑、2,5-二甲基-1,3,4-噻二唑、3-苯基-5-甲基-1,2,4-噁二唑和3,5-二甲基-1,2,4-噻二唑都经历侧链化,在羧化后生成相应的乙酸。1-甲基-3,5-二取代吡唑形成1-甲基衍生物,而1-苯基-3,5-二取代吡唑转化为1-邻苯基-3,5-二取代吡唑。4-甲基异唑主要在C-5处发生化,但也发生环裂解形成1-正丁基-2-基丙-1-烯。含有N—S键的杂环化合物,如3,4-二甲基-1,2,5-噻二唑、4-甲基-5-苯基-1,2,3-噻二唑和3,5-二甲基异唑,在原子上发生亲核攻击,导致环裂解。3,5-二甲基异唑产生2-正丁代戊-2-烯-4-酮。3-甲基-5-苯基-1,2,4-噁二唑通过加成到偶氮亚胺键生成3-甲基-5-苯基-5-正丁基-1,2,4-二氢噁二唑。讨论了这些化的结果。3-甲基-5-甲基异噁唑被转化为各种衍生物。核磁共振光谱分析用于确定产物的身份。

    A new approach for an efficient metal-free synthesis of 1,2,4-thiadiazoles from primary thioamides using visible light and air in the presence of eosin Y as a photoredox catalyst is reported. The protocol involves an aerobic oxidative cyclization of thioamides via the formation of C–N and C–S bonds to afford excellent yields of the products in a simple one-pot operation under mild conditions.
