Diterpenoid (poly)esters and a ring A-seco-phorboid from the aerial parts of Euphorbia macroclada Boiss

Euphorbia macroclada Boiss., a spurge endemic to the Iranian plateau, afforded four pre-myrsinane polyesters, three α-phorboids and one A-seco-phorboid, a type of compound so far unreported within natural products. All new compounds were structurally elucidated by spectroscopic methods, and especially 2D NMR measurements.
