摘要

A new synthesis of pteroylglutamic acid is described in which diethyl N-tosyl-p- aminobenzoyl-L-glutamate is alkylated with 2, 3-oxidopropionaldehyde diethyl acetal, the product oxidized and condensed with 2, 4, 5-triamin0-6. hydroxypyrimidine. Detosylation of this product with hydrogen bromide in acetic acid in the presence of phenol gives the final product in good yield.
