In accordance with the above procedure, but where, in place of 3,4-dimethyl-2-pentenoyl chloride, there is utilized benzoyl chloride, trimethoxybenzoyl chloride or cinnamoyl chloride there is obtained the corresponding 3-ester or 3,15-diester. Similarly, but where, in place of bruceolide, there is utilized brusatol and as an acid chloride there is utilized succinoyl chloride, glutaroyl chloride and acetyl chloride, there is obtained 3,3-bisbrusatolyl succinate, 3,3-bisbrusatolyl glutarate and 3,11,12-brusatolyl triacetate, 3, 11, 12 bis brusatolyl triacetate can also be prepared by acetylation with pyridine in acetic anhydride.
