摘要：
A COMPOUND OF THE FORMULA:
2-R4,2-R5,5-R1,8-(R2-CH(-COO-R)-)-3A,4,7,7A-TETRAHYDRO-
4,7-METHANO-1,3-BENZODIOXOLE
WHEREIN R IS ALKYL OF 1 TO 8 CARBON ATOMS, INCLUSIVE, R1 IS ALKYL OF 1 TO 4 CARBON ATOMS, R2 IS HYDROGEN OR ALKYL OF 1 TO 4 CARBON ATOMS, AND R4 AND R5 ARE HYDROGEN, ALKYL OF 1 TO 4 CARBON ATOMS, INCLUSIVE OR PHENYL, WITH THE PROVISO THAT ONLY ONE OF R4 AND R5 IS PHENYL, IS PRODUCED IN A MULTISTEP REACTION. THE COMPOUND IS AN INTERMEDIATE FOR ELENOLIC ACID.
