Wetting Bate

Hercules Kymene 557 is the cationic, water-soluble, wet strength resin, which conservators know because of its use in the manufacture of calcium carbonate filled P/D paper. In its synthesis, a condensation polymer of adipic acid and diethylene triamine is reacted with epichloro-hydrin to introduce reactive epoxy groups. The behavior of Kymene in dispersed fiber has been investigated by Bates (6,7).

Roderick W. Bates of Nanyang Technological University found (J. Org. Chem. 2008, 73, 8104), in a synthesis of (-)-Mintlactone 29, that the diastereocontroUed reductive cyclization of 27 to 28 worked best in wet DMF. Susianu Kobayashi of the Tokyo University of Science showed (Chemistry Lett. 2008, 37, 770), en route to (-)-Gleenol 32, that the Claisen rearrangement of 30 deUvered the cyclohexene 31 with high diastereocontrol. Barry B. Snider of Brandeis University prepared (J. Org. Chem. 2008, 73, 8049) (-)-Vibralactone C 36 from 33, available from o-anisic acid by the Schultz protocol.
