  • The Preparation of<i>N</i>-Acylpyrazoles and Their Behavior Toward Alcohols
    作者:Choji Kashima、Hajime Harada、Isanobu Kita、Iwao Fukuchi、Akira Hosomi
    DOI:10.1055/s-1994-25406

    According to four different methods, various types of N-acylpyrazoles were prepared from the corresponding pyrazoles and carboxylic acids or their acid chlorides. Although N-acylpyrazoles were inert to alcohols under neutral or weakly basic conditions, the alcoholysis was dramatically accelerated by the action of strong acid or base. On the basis of these chemical properties, the regioselective synthesis of methyl benzyl 2,2-dimethylglutarate was achieved by selective protection and functionalization of a carboxylic acid derivative using N-acylpyrazoles.
    根据四种不同的方法,从相应的吡唑羧酸或其酰制备了多种类型的N-酰基吡唑。尽管在中性或弱碱性条件下,N-酰基吡唑对醇呈惰性,但强酸或碱的作用下,醇解反应显著加速。基于这些化学性质,通过选择性保护和功能化羧酸生物,成功实现了甲基苄基2,2-二甲基戊二酸酯的区域选择性合成。
  • Highly regioselective and practical synthesis of 1-acyl-5-hydroxypyrazolines and 1-acyl pyrazoles from 1,2-allenic ketones and hydrazides
    作者:Shenghai Guo、Jiliang Wang、Dongqiang Guo、Xinying Zhang、Xuesen Fan
    DOI:10.1016/j.tet.2012.07.046
    日期:2012.9
    A mild and highly regioselective synthesis of 1-acyl-5-hydroxypyrazolines has been achieved through the condensation of 1,2-allenic ketones with hydrazides in the absence of any catalyst. Moreover, the obtained 1-acyl-5-hydroxypyrazolines can be easily transformed into 1-acyl pyrazoles under the promotion of BF3·Et2O. It was also found that 1-acyl pyrazoles can be produced directly from allenic ketones
    在不存在任何催化剂的情况下,通过1,2-炔酮与酰的缩合,已实现了1-酰基-5-羟基吡唑啉的温和且高度区域选择性的合成。此外,在BF 3 ·Et 2 O的促进下,所获得的1-酰基-5-羟基吡唑啉可以容易地转化为1-酰基吡唑。还发现1-酰基吡唑可以直接由烯丙基酮和酰通过一锅法。
