Abstract
Official abstract text for this publication.
A hydrogenated Diels-Alder adduct of the formula (III) a hydrogenated Diels-Alder adduct of the formula (IV) and a lactone compound of formula (V) are disclosed and described.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hydrogenated Diels-Alder adduct of the formula (IV) wherein X and Y are different and independently selected from the group consisting of —CHO, —CH 2 OR 3 and —COOR 4 , wherein R 3 is selected from the group consisting of hydrogen, alkyl, aryl, alkaryl, aralkyl, alkylcarbonyl and arylcarbonyl, and wherein R 4 is selected from the group consisting of hydrogen, alkyl and aryl. 2. A lactone compound of formula (V) wherein Y is hydrogen and X is selected from the group consisting of alkyl, aralkyl, —CHO, —CH 2 OR 3 , —CH(OR 4 )(OR 5 ), —COOR 6 , wherein R 3 , R 4 and R 5 are the same or different and are independently selected from the group consisting of hydrogen, alkyl, aryl, alkaryl, aralkyl, alkylcarbonyl and arylcarbonyl, or wherein R 4 and R 5 together form an alkylene group, and wherein R 6 is selected from the group consisting of hydrogen, alkyl and aryl. 3. The lactone compound according to claim 2 , wherein Y is hydrogen and X is selected from the group consisting of alkyl, aralkyl, —CHO, or —CH 2 OR 3 , wherein R 3 is selected from the group consisting of hydrogen, alkyl and aryl.
