Abstract
A number of derivatives of peganine and vasicinone have been obtained: 4-hydroxy-9-O-methylpeganine, isodihydrovasicinone, and 9-methoxy-, 9-phenoxy-, and 9,9-dichlorodeoxyvasicinones. An unusual ease of reduction of vasicinone and of 9-chlorodeoxyvasicinone has been found. An introduction of a hydroxy group into position 4 of a dihydroquinazoline alkaloid with the aid of sodium hydride has been detected.
