, p. 5677 - 5684 (2006)
The synthesis of orttho-(trimethylsilyl)triphenylenyl triflates 7 is described. Fluoride-induced decomposition of these triflates leads to the generation of didehydrotriphenylenes (triphenylynes). 6. These arynes undergo [4+2] cycloadditions with dienes to afford the corresponding Diels-Alder adducts or palladium-catalyzed formal [2+2+2] cycloadditions to afford extended triphenylenes.
New total synthetic method of natural product moracin S
-
Paragraph 0038-0042, (2016/10/20)
The present invention relates to a novel total synthesis method of natural material moracin S of which a small amount exists in African mulberries and exhibiting antioxidative and antifungal activities, wherein moracin S can be effectively synthesized from a cheap 4-bromoresorcinol compound through seven-stage reaction including regioselective acetylation, propargylation, reduction, Sonogashira coupling, water-accelerated [3,3]-sigmatropic rearrangement and benzofuran formation, hydrolysis, and demethylation, etc.COPYRIGHT KIPO 2015

An efficient and practical synthesis of natural moracins, which have diverse range of biological properties including anticancer, antioxidant, and antibacterial activities, has been achieved using Pd(OAc)2/P(tBu)3-HBF
Lipase-catalyzed regioselective protection of hydroxyl groups in aromatic dihydroxyaldehydes and ketones

, p. 3143 - 3148 (2007/10/02)
Pseudomonas cepacia lipase catalyzes the acetylation in organic solvent of dihydroxyaldehydes and ketones using vinyl acetate as acyl donor. The method is completely regioselective and allows to obtain partially acetylated compounds different from those obtained by enzymic hydrolysis of polyacetoxy arylaldehydes and ketones.
