Abstract

(8) Reif, L.; Hacker, H. Macromolecules 1984, 17, 952.(9) All starting materials were obtained from Aldrich and used as received. Compounds 2, 5, 7, 9, 13, and 15 were synthesized by alkylation of the appropriate starting ketone using lithium diisopropylamide in THF at or below-40'C followed by either methyl iodide, allyl iodide, or 5-iodopentene (from 5- bromopentene, Aldrich). Dimethyl malonate was diallylated in a similar fashion at-65 OC ...
