TL;DR: In this paper, a total synthesis of atroviridin (1 ) based on biosynthetic principles is presented. But the synthesis of the natural product was constructed by coupling aryl bromide 8 with aldehyde 7 and subsequent intramolecular conjugate addition on a quinone precursor.
Abstract: A total synthesis of atroviridin ( 1 ) based on biosynthetic principles is presented. The tetracyclic xanthone structure of the natural product was constructed by coupling aryl bromide 8 with aldehyde 7 and subsequent intramolecular conjugate addition on a quinone precursor. Bromide 8 was produced from aldehyde 9 via a sequence of steps involving Baeyer–Villiger oxidation and Claisen cyclization.
Journal ArticleDOI
TL;DR: In this paper , a study on the whole plants of a Gentianaceous medicinal plant, Canscora lucidissima, gave one new acylated iridoid glucoside, canscorin A (1), and two new xanthone glycosides (2 and 3).

TL;DR: The title compound (trivial name brasixanthone B), C23H22O5, isolated from Calophyllum gracilentum, is characterized by a xanthone skeleton of three fused six-membered rings plus an additional fused pyrano ring and one 3methyl-but-2-enyl side chain this paper .
Journal ArticleDOI
TL;DR: In this paper, reaction of dienamine with dimethyl acetylenedicarboxylate and dimethyl maleimide was shown to yield xanthone and chromone, respectively.
Abstract: Reaction of dienamine 2 (R = H and Me) with N -phenylmaleimide or chromone 3 gives xanthones 5 and 8, respectively, through initial [4 + 2] cycloaddition, whereas reaction with dimethyl acetylenedicarboxylate affords xanthone 13.
