Abstract

NEW MATERIAL:A compound shown by the formula I (R1 is lower alkyl; R2 is H or lower alkyl).
EXAMPLE: Ethyl-1-ethoxycarbonyl-3-oxo-2-piperidine acetate.
USE: A synthetic intermediate for an azaerythrinan derivative (novel substance) shown by the formula II having depressant actions on central nervous system, especially strong pain-killing actions.
PROCESS: A compound shown by the formula III is converted into an enamine derivative shown by the formula IV (a group shown by the formula V is dialkylamine or ring amine, e.g., pyrrolidino, piperidino, morpholino, etc.), which is reacted with a haloacetic acid derivative shown by the formula X-CH2CO2R2 (X is halogen), and hydrolyzed so that only an enamino group is removed, to give a compound shown by the formula I.
