Pyridine: the scaffolds with significant clinical diversity
2022年5月5日 · Introduction. Pyridine (C 5 H 5 N), an isostere of benzene, is used as a precursor for synthesizing target pharmaceuticals and agrochemicals. Besides, it is a key solvent and reagent. The term ‘pyridine’ is a derivative from a Greek word, and is the grouping of two words “pyr” denotes fire and “idine” is applicable for aromatic bases.
