BROMOISOVALERIC ACID

Bromo-2-ethoxyethane, 23, 32 3-Bkomo-4-hydroxytoluene, 23,11 -Bromoisocaproic ACID, 21, 74 a-BROMOISOvaleric acid, 20, 106 Bromomesitylene, 21, 77... [Pg.53]

Valine has been prepared by the action of alcoholic ammonia on a-chloroisovaleric acid 1 by the action of aqueous ammonia on a-bromoisovaleric acid 2 by the action of ammonia and ammonium carbonate on a-bromoisovaleric acid 3 by heating iso-propyl-malonylazidic acid and subsequent hydrolysis 4 by the action of ammonia and hydrogen cyanide on isobutyraldehyde followed by hydrolysis.5 a-Bromoisovaleric acid has been prepared in several ways as described in an earlier volume.6... [Pg.55]

Direct bromination of an acid yields the a-substituted product when red phosphorus or phosphorus halides are used as carriers. The procedure is illustrated by the preparation of a-bromo-n-caproic acid (89%) and a-bromoisovaleric acid (89%)." An excellent laboratory preparation of bromoacetic acid is furnished by a modification of the reaction in which acetic anhydride with pyridine is used as the catalyst. ... [Pg.56]
