  Ultrasound assisted reductive cleavage of sesquiterpene γ-enonelactones

  摘要：

  Ultrasound enhances the rate of reductive cleavage of the C-6-oxygen bond of several cis- and trans- sesquiterpene gamma-enonelactones. Interestingly ultrasound overrides the stereoelectronic requirements for the reductive cleavage of the most usually occurring sesquiterpene trans-lactones.

  Synthesis of the reported structure of herbolide I and its C-11 epimer from artemisin

  摘要：

  Artemisin (1) was converted into 12 (the reported structure for herbolide I) and its C-11 epimer 19 via a synthetic pathway involving a functionality transfer from C-8 to C-9 and an A-ring refunctionalization. The H-1 and C-13 NMR data of synthetic products 12 and 19 reveal that the assigned structure of the natural herbolide I is erroneous.

  Ultrasound enhances the rate of reductive cleavage of the C-6-oxygen bond of sesquiterpene enonelactones. trans-Eudesmanolides 1c-1g, cis-eudesmanolides 2a-2c, and trans-guaianolides 4a-4d react with Zn in acetic acid-H2O under sonochemical conditions to afford the corresponding sesquiterpene. acids 3a-3g and 5a-5d, respectively in good yields. Starting from 5d two natural guaianes 1 alpha ,7 alpha ,10 alphaH-guaian-4, 11-dien-3-one (6) and hydrocolorenone (7) have been prepared in good yields through a straightforward sequence.
