7-methoxycoumarins from Micromelum minutum

Chemical investigation of an Assamese collection of Micromelum minutum gave four known coumarins (osthol, micromelin, murralongin and murrangatin) and five new coumarins, dihydromicromelin A and B, acetyldihydromicromelin A, the threo diastereomer of murrangatin, the 7,12-ether of 5,7-dihydroxy-3,6,...
