Abstract

1,239,345. Hydrazides. F. HOFFMANNLA ROCHE & CO. A.G. 14 Aug., 1969 [16 Aug., 1968], No. 40605/69. Heading C2C. [Also in Division A5] The invention comprises N<SP>1</SP>-tyrosine-N<SP>2</SP>- (2,3,4-trihydroxybenzyl)-hydrazide (I) and N<SP>1</SP>- tyrosine - N<SP>2</SP> - (2,3,4 - trihydroxybenzylidene)- hydrazide (II) and their acid addition salts. Compound I and its acid addition salts is prepared by (a) hydrogenating compound II or an acid addition salt thereof, or (b) converting by methods known per se the group or groups convertible into the hydroxy group and/or into the α - amino - # - (p - hydroxyphenyl) - ethyl group in a compound of the Formula III in which R 1 , R 2 and R 3 are hydroxy groups or groups convertible into hydroxy groups and R 4 is the α-amino-#-(p-hydroxyphenyl)-ethyl group or a group convertible into the α-amino-#- (p-hydroxyphenyl)-ethyl, at least one of R 1 , R 2 , R 3 , R 4 and R 5 being different from the hydroxy group or from the α-amino-#-(p-hydroxyphenyl)- ethyl group, or in an acid addition salt of such a compound, into the hydroxy group and/or into the α-amino-#-(p-hydroxyphenyl)-ethyl group and, if desired, splitting a racemate obtained into the optical antipodes and, also if desired, converting a base obtained into an acid addition salt. The groups convertible into hydroxy groups are benzyloxy groups, acetal groups which are derived from acetaldehyde, acetone or tetrahydropyran, or acyloxy groups. The groups convertible into the α-amino-#-(phydroxyphenyl)-ethyl group are groups of the formulµ HOOC-C(NH 2 )R 5 , -CHR 5 R 6 and -C(=R 7 )R 5 , in which R 5 is the α-amino-#-(phydroxyphenyl) - ethyl group, R 6 is Compound II is prepared by reacting an acid addition salt of tyrosine hydrazide with 2,3,4- trihydroxybenzaldehyde. Starting materials of Formula III are prepared by reacting a correspondingly substituted tyrosine hydrazide with a correspondingly substituted benzaldehyde and subsequently hydrogenating the benzylidene compound obtained.
