Micromelosides A-D, four new coumarins from the stem bark of Micromelum falcatum.
TL;DR: Four new coumarins, micromelosides A–D, together with four known coumarics were isolated from the stem bark of Micromelum falcatum by means of 1D and 2D NMR techniques, including 1H‐1H COSY, HSQC, HMBC and NOE difference.

Coumarins of Merrillia caloxylon
TL;DR: From the roots of Merrillia caloxylon, the five isoprenylcoumarins (−)-sibiricin, (−)-phebalosin and (−)-mexoticin were isolated as discussed by the authors.
Journal ArticleDOI
Acid rearrangements of the murrangatins
TL;DR: In this article, an acid-catalyzed rearrangement of threo- murrangatin gave coumarins with tetrahydrofuryl side-chains, differences in reactivity from the erythro- isomer being attributed to stereoelectronic control.
Journal ArticleDOI
A convenient synthesis of phebalosin: first total synthesis of murraxocin
TL;DR: A convenient and high yielding total synthesis of phebalosin has been achieved in four linear steps from commercially available umbelliferone using a Corey–Chaykovsky reaction to construct the isopreneepoxide unit.
