title: 2H-1-benzopyran derivatives with platelet antiaggregating and other activities.
abstract: The synthesis of some N,N-disubstituted 4-amino-5,6,7,8-tetrahydro-3,6- diphenyl-2H-1-benzopyran-2-ones by reaction of phenylchloroketene with a series of N,N-disubstituted 2-aminomethylene-4-phenylcyclohexanones, followed by dehydrochlorination in situ of the primary adducts with DBN, is described. Some compounds showed a platelet antiaggregating activity in vitro superior or comparable to that of acetylsalicylic acid and an appreciable antiarrhythmic activity, as well as weak anti-inflammatory and local anesthetic activities in rats and mice.
