A method for the synthesis of derivatives of the lead structures euniolide (1), 12,13-bisepieupalmerin (2), and eupalmerin acetate (3) containing tetrahydrofuran and tetrahydropyran ring systems was developed on the basis of alkali-induced intramolecular oxacyclizations. Representatives of the new analogues were submitted to the in vitro antitumor cell-line-screening program of the National Cancer Institute (NCI). While it was shown that a variety of structural modifications are possible, these transformations led typically to nontoxic synthetic cembranoids.
Interconversion of Cembranolide &δ- and &γ-Lactones: Synthesis of the C-1 Epimer of Isolobophytolide
Marshall, James A.,Karas, Lawrence J.,Coghlan, Michael J.
, p. 699 - 701 (2007/10/02)
The δ-lactone cembranolide diterpene crassin alcohol (2) has been converted to an isomeric γ-lactone isocrassin alcohol (6) by a sequence involving kinetically controlled addition of benzenethiol to the conjugated lactone double bond followed by base-prom
