Metabolites of the higher fungi. Part 29. Maldoxin, maldoxone, dihydromaldoxin, isodihydromaldoxin and dechlorodihydromaldoxin. A spirocyclohexadienone, a depsidone and three diphenyl ethers: Keys in the depsidone biosynthetic pathway from a member of the
Asymmetric Total Synthesis of (-)-Maldoxin, a Common Biosynthetic Ancestor of the Chloropupukeananin Family
The total synthesis of pestheic acid based on an intramolecular SNAr reaction without a nitro group and the asymmetric synthesis of (-)-maldoxin by a catalytic enantioselective oxidative dearomatization of pestheic acid are described. The reactivity of (-)-maldoxin as a diene in the Diels-Alder reaction is also investigated.
Syntheses of chloroisosulochrin and isosulochrin and biomimetic elaboration to maldoxin, maldoxone, dihydromaldoxin, and dechlorodihydromaldoxin
An efficient synthesis of chloroisosulochrin was accomplished using a novel ortho-selective chlorination of a phenol with sulfuryl chloride and 2,2,6,6-tetramethylpiperidine as the key step. Further elaboration by a biomimetic route converted chloroisosul
