2-substituted 8-methylpyrimido[4,5-b][1,5]oxazocine derivatives. Axially chiral 8-methylpyrimido[4,5-b][1,5]oxazocines bearing a substituent at the C-2 position were synthesized and evaluated as NK(1) antagonists. The results revealed that (aR, 8S)-stereochemistry and the substituent at the C-2 position are important for NK(1) receptor recognition.
