摘要

During a search for benzodiazepine receptor modulators, a highly potent adenosine antagonist (CGS 15943) was discovered. The compound was defined as a resonance- stabilized hybrid of the canonical structures 9-chloro-2-(2-furyl)[1, 2, 4] triazolo [1, 5-c] quinazolin-5-amine (2a) and 9-chloro-2-(2-furyl)-5, 6-dihydro [l, 2, 4] triazolo [1, 5-c]- quinazolin-5-imine (2b). Spectroscopic evidence and chemical reactivity in polar media ...
