that the analgetic properties displayed by compounds 1--3 are associated, mainly, with the 2-amino-1,3-thiazine ring system. In the 2-acylimino series, evidence is presented suggesting a contribution to the observed activity on the part of the spiroannulated ether ring as well. Both 1a and its p-fluorobenzoyl derivative 33 exhibit analgesicactivity in the rat tail-flick assay.
