Four new bioreductive esters (7-10) have been synthesized. Their structures composed of trimethyl lock containing quinone propionic acid with an ester linkage to the fungal cytotoxic compounds; preussomerin G (1), preussomerin I (2), phaseolinone (3) and phomenone (4). The synthesized esters are aimed to act via reductive activation specifically at the cancer cells, resulting from hypoxia and overexpression

Stereoselective synthesis of several oxygenated eremophilane sesquiterpenes as phytotoxins, (+)-gigantenone 1, (+)-phomenone 2 and (+)-phaseolinone 3, was achieved in short steps from (+)-sporogen-AO 1 (13-desoxyphomenone) 4.
