A New Secondary Metabolite from Alternaria Alternata: Structure Elucidation and Total Synthesis of Altenuic Acid IV
Kohler, Dominik,Podlech, Joachim
, p. 1748 - 1753 (2019)
A putative intermediate in the biosynthesis of altenuic acids I–III was isolated from Alternaria alternata in the 1950ies and a sample survived over the decades. This resorcylic lactone named altenuic acid IV is a composite of a resorcylic and a muconic a

The total synthesis of decarboxyaltenusin (5'-methoxy-6-methyl-[1,1'-biphenyl]-3,3',4-triol), a toxin produced by various mold fungi, has been achieved in seven steps in a yield of 31% starting from 4-methylcatechol and 1-bromo-3,5-dimethoxybenzene, where

Paragraph 0051-0053, (2017/05/03)
The invention discloses a preparation method of 4,5-dihydroxyl-2-methyl benzoic acid and belongs to the fields of fine chemical engineering and medicine intermediates. The preparation method of 4,5-dihydroxyl-2-methyl benzoic acid comprises the following steps: preparing an intermediate III or V by taking 4-methylbenze-1,2-diphenol as a raw material, then preparing an intermediate IV by virtue of the intermediate III or V, then transforming the intermediate IV into an intermediate II, and finally preparing 4,5-dihydroxyl-2-methyl benzoic acid by virtue of the intermediate II. The preparation method of 4,5-dihydroxyl-2-methyl benzoic acid has the advantage that the problems that raw materials are difficult to acquire, byproducts are many, yield is low, cost is high, steps are miscellaneous, safety can not be guaranteed and serious pollution is produced in the prior art are overcome.

, p. 11067 - 11073 (2007/10/03)
We have developed novel fluorescence probes for sodium cation based on photoinduced electron transfer (PeT). In this study, we rationally designed new probes and succeeded in achieving fluorescence enhancement upon sodium ion binding by reducing the HOMO
