The U.V. and I.R. absorption spectra of yangonine (IIa), pseudoyangonine (IIIa) and related compounds have been recorded. The absorption of the compounds of type II proves for their structure as 2H-pyran-2-one, and the absorption of the compounds of type III—their structure as 4H-pyran-4-one.
记录了仰光氨酸(IIa),假仰光氨酸(IIIa)和相关化合物的UV和IR吸收光谱。II型化合物的吸收证明其结构为2H-吡喃-2-酮,III型化合物的吸收证明其结构为4H-吡喃-4-酮。
