  A novel strategy for the cross dehydrogenative coupling (CDC) of acetophenone hydrazones and aldehydes has been developed for the synthesis of highly substituted pyrazoles. This work, for the first time, uses elemental sulfur as a promoter as well as a hydrogen acceptor in effecting the Csp(3)-Csp(2) bond formation via C-H activation.

  苯乙酮hydr和醛类的交叉脱氢偶联（CDC）的新策略已经开发出来，用于合成高度取代的吡唑。这项工作第一次使用元素硫作为促进剂以及氢受体，以通过CH活化作用实现Csp（3）-Csp（2）键的形成。

  Embodiments of the presently-disclosed subject matter include activators of HssRS that induce endogenous heme biosynthesis by perturbing central metabolism. These molecules are toxic to fermenting S. aureus , including clinically relevant small colony variants (SCVs). The utility of targeting fermenting bacteria is exemplified by the fact that this compound prevents the emergence of antibiotic resistance, enhances phagocyte killing, and reduces S. aureus pathogenesis. This small molecule is a powerful tool not only for studying bacterial heme biosynthesis and central metabolism, but also establishes targeting of fermentation as a viable antibacterial strategy.

  A facile and efficient copper‐promoted oxidative intramolecular C–H amination of hydrazones for the synthesis of 1H‐indazoles and 1H‐pyrazoles was developed using a tracelessly cleavable directing group. This reaction is characterized by its mild conditions, operational simplicity, readily available reagents, and excellent yields. A tentative mechanism for Cu‐mediated C–H‐oxidative amination was proposed
