What coupling reactions can I run with 4-Chloro-3-hydroxy-butyric acid methyl ester?
As a chlorinated compound, 4-Chloro-3-hydroxy-butyric acid methyl ester is an excellent substrate for palladium-catalyzed cross-coupling reactions including Suzuki, Heck, Negishi, Sonogashira, and Buchwald–Hartwig amination. It can also be used for Grignard reagent preparation, metal–halogen exchange with organolithium reagents, and nucleophilic substitution reactions.
What coupling reagents work best with 4-Chloro-3-hydroxy-butyric acid methyl ester?
For amide bond formation from the carboxylic acid in 4-Chloro-3-hydroxy-butyric acid methyl ester, HATU/DIPEA is recommended for peptide coupling (high yield, low epimerization). EDC/HOBt is a cost-effective alternative for non-peptide amides. T3P (propylphosphonic acid anhydride) offers excellent atom economy with easy workup. For ester formation, DCC/DMAP (Steglich conditions) or Mitsunobu conditions are standard.
How should I store 4-Chloro-3-hydroxy-butyric acid methyl ester?
Store at recommended temperature in a well-sealed container. Protect from moisture and strong bases. Store at room temperature in a tightly sealed container. Protect from moisture and strong bases. Store at room temperature in a tightly sealed container away from heat and open flame.
