Stereoselective Synthesis of Melatonin Receptor Agonist Ramelteon via Asymmetric Michael Addition
摘要:
Highly enantioselective asymmetric Michael addition was used to synthesize ramelteon and its analogue. The asymmetric strategy provides an efficient approach for the medicinal modification of ramelteon with high ee value.
