Microbial synthesis of pyrogallol using genetically engineered ...
网页2018年1月1日 · Here, we report establishment of a novel and efficient biosynthetic pathway for the synthesis of pyrogallol. First, we identified and characterized an efficient 2,3-dihydroxybenzoic acid (2,3-DHBA) 1-monoxygenase from a series of oxygenases and hydroxylases based on the structural similarity in the …
Pyrogallol - Wikipedia
网页In alkaline solution, pyrogallol undergoes deprotonation. Such solutions absorb oxygen from the air, turning brown. This conversion can be used to determine the amount of oxygen in a gas sample, notably by the use of the Orsat apparatus .
Complex Natural Products Derived from Pyrogallols - PubMed
网页Only in the last ten years have critical insights of pyrogallol chemistry from the mid-twentieth century been applied to modern natural product synthesis. Historical studies of pyrogallol chemistry, including [5+2], [4+2], and formal [5+5] cycloadditions are discussed here and reactivity guidelines established.
Complex Natural Products Derived from Pyrogallols
网页2022年4月14日 · In this chapter, we will give an overview of historic synthesis studies on pyrogallols and their chemistry focusing on the studies of the purpurogallin cascade and the Perkin dimer. A special focus will be on the [5+2] cycloadditions of hydroxy- o- quinones derived by oxidation of pyrogallols [2, 5, 6]. Fig. 1.
