New rearranged neo-clerodane diterpenoids from Teucrium alyssifolium

Four new diterpenoids alysine A, alysine B, 3-deacetylalysine B and alysine C with a novel rearranged neo-clerodane skeleton were isolated from Teucrim alyssifolium. The relative structures were determined by X-ray analysis and other spectroscopic methods including 1D and 2D NMR experiments (APT, SI...

Description
Summary:Four new diterpenoids alysine A, alysine B, 3-deacetylalysine B and alysine C with a novel rearranged neo-clerodane skeleton were isolated from Teucrim alyssifolium. The relative structures were determined by X-ray analysis and other spectroscopic methods including 1D and 2D NMR experiments (APT, SINEPT, HETCOR and HMBC).
