C-geranyl compounds from Mimulus clevelandii.
Fractionation of the MeCOEt extract of Mimulus clevelandii yielded the novel 4-geranyl-5-hydroxy-2(3H)-benzofuranone (1) and the five known 6-geranylflavanones diplacone (2a), 3'-O-methyldiplacone (2b), diplacol (2c), mimulone (2d), and 3'-O-methyldiplacol (2e). 2D-NMR methods required revision of assignments for diplacone and diplacol and resolved the uncertainty in the site of methylation for the methyl ethers.
