| titleOfInvention | PROCEDURE FOR THE PREPARATION OF 5'-PHOSPHA-TO DERIVATIVES OF PYRIDOXAL. |
| abstract | The invention comprises pyridoxal-51-phosphate derivatives of formula <FORM:1111876/C2/1> where R is hydrogen, methyl or ethyl. The compounds may be prepared by reacting pyridoxal-51-phosphate or a derivative thereof in which the aldehyde group is modified so that it is liberated in the presence of an acidic medium, with an aldehyde RCHO in aqueous acidic solution. The compounds may be reconverted to pyridoxal - 51 - phosphate by hydrolysis with aqueous mineral acid or by reaction with aqueous ammonia, and pyridoxal-51-phosphate may be purified and/or isolated by first forming a compound of the above formula and then reconverting it. In Examples pyridoxal oxazolidine is phosphorylated with polyphosphoric acid and then reacted with formaldehyde, paraldehyde and propionaldehyde, and pyridoxal-51-phosphate-oxime and pyridoxal-51-phosphate semicarbazone are reacted with formaldehyde pyridoxal-51-phosphate is obtained from some of the products by hydrolysis with hydrochloric acid and by reaction with ammonia. |
