Cyclopropylglycine derivatives and agonists for metabotronic L-glutamate receptors

摘要

A cyclopropylglycine derivative having the following formula:and an intermediate compound for the synthesis of the cyclopropylglycine derivative are novel compounds. The cyclopropylglycine derivative shows a selectivity higher than that of the known agonists to metabotropic L-glutamate receptors, and therefore is a metabotropic type agonist to L-glutamate which has excellent characteristics.
