Abstract: Novel epoxyalkoxy-containing [4.4] spirodilactams having ring nitrogen atoms in the 1- and the 6- ring positions and having a substituent on each ring nitrogen atom, at least one of which substituents contains an epoxyalkyl moiety. Such epoxy compounds are produced by reaction of a 1-halo-2,3-epoxyalkane and the corresponding hydroxy-containing spirodilactam followed by treatment with strong base.

Abstract: New interphenylene prostaglandin (PGH) analogs are prepared by a method which involves reacting a bicyclic olefin, an acetylene compound and a benzylic halide together, in the presence of a palladium(O) catalyst in a single-step synthesis. By this technique a large number of new interphenylene PGH analogs can be prepared, which are useful as inhibitors of arachidonic acid induced platelet aggregation.

Abstract: Process for the preparation of organic isocyanates in which a furoxan is heated in the presence of a vicinal diketo compound containing two adjacent keto carbonyl groups. When the furoxan ring is fused to an organic ring system di-isocyanates are produced. An adduct of the furoxan and the diketo compound may be isolated from the reaction mixture and used as a stable isocyanate precursor, for example, a "one-pot" polyurethane composition.
