Abstract

NEW MATERIAL:A compound of formula I (R1 is OH or O-lower alkyl; R is H, lower alkyl or benzyl; R3 and R4 are OH or lower alkyl). EXAMPLE:A compound of formula II. USE:An antitumor agent, anti-inflammatory agent and immunological activating agent. PROCESS:A phenylalanine of formula III is reacted with ethanol, etc. to give an ester derivative of formula IV, which is then reacted with a trichlorogermylpropionyl chloride of the formula Cl3GeCH2CH2COCl to afford a trichloro derivative of formula V. The resultant trichloro derivative is then hydrolyzed to afford a compound of formula (R1 is O-C2H5; R2 is CH2C6H5; R3 and R4 are H).
