Paragraph 0039-0043, (2019/09/14)
The invention discloses a method for preparing 1,3,5,8-tetrahydroxy xanthone and 1,3,7,8-tetrahydroxy xanthone. The method comprises the following steps: by taking 1,2,4-trimetoxybenzene as an initialraw material, and adding n-butyllithium and a chloro-ca

A new and efficient strategy was developed for the preparation of 1,2,4-trimethoxybenzene (3, a powerful attractant of Euglossini bees) and its C-3 derivatives (7a-j), from vanillin (2) in 56% overall yield.

An efficient, flexible, and stereoselective convergent route for constructing the trans-10-hydroxy-1,1-dimethyloctahydrodibenzo[a,d]cyclohepten- 7-ones (5a-c) was achieved via intramolecular Heck reaction. This strategy has been successfully implemented for the syntheses of (±)-komaroviquinone (3) through (±)-coulterone dimethyl ether (5c) and (±)-faveline methyl ether (1a).
