Abstract
NEW MATERIAL:A compound of formula I [R1 and R2 are G or lower alkoxyl; R3 is lower alkyl or group of formula V (m is 1 or 2)]. EXAMPLE:15,16-Dimethoxy-2-methyl-10-oxo-2-azaerythrinan. USE:A useful medicine having a central nervous system depressant action, particularly a powerful analgesic action. PROCESS:A compound of formula II is reacted with a phenylacetic acid derivative of formula III [X is Cl, Br or a carbonate of -OCO2R4 (R4 is alkyl)] in an inert organic solvent, e.g. chloroform, in the presence of a deacidifying agent under cooling with ice to give a compound of formula IV, which is then subjected to the ring closure under acidic conditions of a mineral acid, e.g. sulfuric acid, and heating at 80-160 deg.C to afford the compound of formula I.
