Abstract
NEW MATERIAL:A compound shown by the formula I (R1 is acryl; R2 is lower alkyl).
EXAMPLE: 2-Methylene-3- ethoxycarbonyl- 3-( 5'-acetoxy-4'-methyl-3'-pentenyl )-bicyclo[2.2.1] heptane.
USE: An intermediate for synthesizing β-santalol, a main ingredient of sandalwood oil.
PROCESS: A 2-methyl-3-alkoxycarbonyl-bicyclo[2.2.1]hepto-2-ene shown by the formula II is reacted with a [2Z]-1-acyloxy-5-halo-2-methyl-2-pentene shown by the formula III (X is Br or Cl) in the presence of an anionic agent (e.g., sodium amide, lithium diisopropylamide, etc.) in a solvent, e.g., tetrahyrdrofuran, etc. at -90W 50°C, to give a compound shown by the formula I.
