1,3 proton transfer catalysts supported by Merrifield resin or Jeffamine gel
6-Chloronicotinic acid was coupled by an amide linkage to Merrifield resin or Jeffamine gel. Nucleophilic displacement of the 6-chloride group by hydroxide gave novel Merrifield resin catalyst 6 or Jeffamine gel catalyst 9 that were successfully used for Henry condensations. The condensation of 4,6-...
