Crystal and molecular structure of 2,3-tetramethylen-3,4-dihydroquinazoline

摘要

The crystal and molecular structure of the alkaolid 2,3-tetramethylen-3,4-dihydroquinazoline hydrochloride was solved by X-ray structure analysis. It was demonstrated that the crystal contains an aqua system similar to those in the isostructural 2,3-trimethylen-3,4-dihydroquinazoline (deoxypeganine), and 2,3-pentamethylen-3,4-dihydroquinazoline hydrochlorides.
