芳香族アルデヒドとα-アミノ酸類の反応に関する研究 (第7報)

抄録

In continuation of previous reports on the reaction of aromatic aldehydes and α-amino acids, α-aminophenylacetic acid was used in place of the previous aliphatic acids. It was found that the reaction also occurred in this case as in equation (1) but there was seen a tendency for the formation of a larger amounts of A-type and C-type bases of formula (I), contrary to the case of aliphatic amino acids. It was also proved by the present series of experiments that water was formed during the reaction when the amino group in the α-amino acid was primary or secondary. A reaction mechanism was proposed for the formation of numerous bases from the present and two preceding experiments by enlarging upon the considerations made in a previous paper.
