Significance

The target molecule is a constrained glutamic acid analogue that mimics L-glutamate, a major excitory neurotransmitter. Potential applications include schizophrenia, depression, anxiety, addiction, pain, epilepsy and neurodegenerative diseases (Parkinson’s and Alzheimer’s). This short, large-scale synthesis (10 steps, 43% overall) features the creation of a cyclopropane ring by an intramolecular epoxide opening by the enolate of an α-fluoro ester (D → E).
