  Synthesis of (+)-pechueloic acid and (+)-aciphyllene. Revision of the structure of (+)-aciphyllene

  摘要：

  1 alpha H,7 alpha H,10 alpha H-Guaia-4,11-dien-3-one and its 1 beta H,10 beta H diastereomer, easily obtained from (+)-dihydrocarvone, are good starting materials for the synthesis of natural guaiane derivatives. Allylic oxidation of the 1 alpha H,10 alpha H isomer gave as main product its 13- hydroxy derivative and a small amount of (+)-7 beta-hydroxy-1 alpha H,10 alpha H-guaia-4,11-dien-3-one, whereas the 1 beta H, 10 beta H diastereomer afforded selectively the (-)-7 alpha-hydroxy-1 beta H,10 beta H enantiomer in excellent yield. From the 13-hydroxy derivative (+)-pechueloic acid and (+)-methyl pechueloate were synthesized. Deoxygenation at C-3 of the 1 beta H,10 beta H guaiadienone afforded a guaiadiene with the reported structure for aciphyllene but its spectral data did not agree with those reported for the natural diene. The structure of natural (+)-aciphyllene has been corrected to 1 alpha H,7 alpha H,10 alpha H-guaia-4,11-diene obtained by deoxygenation of the 1 alpha H,10 alpha H guaiadienone.

  Ultrasound assisted reductive cleavage of eudesmane and guaiane γ-enonelactones. Synthesis of 1α,7α,10αH-guaian-4,11-dien-3-one and hydrocolorenone from santonin

  摘要：

  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.

  All four 7αH-guaia-4,11-dien-3-one diastereomers have been synthesized from the common intermediate 1αH,10α-acetoxy-7αH-guaia-4,11-dien-3-one obtained from (+)-dihydrocarvone. The spectral features of the four diasteromers have been correlated and the structure and absolute configuration of 1βH,10βH,7αH-guaia-4,11-dien-3-one isolated from Pleocarphus revolutus has been confirmed.
