  噻唑和异喹啉结构的比较研究

  摘要：

  为了检验噻唑和异喹啉环在结构上的相似性的想法（可以追溯到Mills和Bmith），详细研究了4-甲基噻唑和3-甲基异喹啉对苯甲醛的行为。已经发现在两种情况下都发生缩合，但是在噻唑衍生物的情况下，这主要产生苯基-[4-甲基噻唑基-（2）]甲醇，而3-苯乙烯基邻苯二酚喹啉在相当的条件下由异喹啉衍生物形成。通过合成验证了这些化合物的结构。

• Copper‐Catalyzed Aza‐Sonogashira Cross‐Coupling To Form Ynimines: Development and Application to the Synthesis of Heterocycles

  AbstractNitrogen‐substituted alkynes, such as ynamines and ynamides, are versatile synthetic building blocks. Ynimines bearing additional nucleophilic and electrophilic centers relative to ynamines and ynamides are expected to have high synthetic potential. However, their chemical reactivity remains unexplored owing mainly to the lack of synthetic accessibility. We report herein a versatile copper‐catalyzed synthesis of ynimines from readily available O‐acetyl ketoximes and terminal alkynes. A wide range of O‐acetyl ketoximes derived from diaryl ketones, aryl alkyl ketones and dialkyl ketones underwent cross‐coupling with a diverse set of terminal alkynes to afford the ynimines in good to excellent yields. An unprecedented [5+1] heteroannulation reaction exploiting the reactivity of the ynimine generated in situ was subsequently developed for the synthesis of medicinally important heterocycles, including isoquinolines, azaindoles, azabenzofurans, azabenzothiophenes and carbolines.
