摘要:An ylide-based aza-Payne rearrangement of 2,3-aziridin- 1 -ols leads to an efficient process for the preparation of pyrrolidines. The aza-Payne rearrangement under the basic reaction conditions favors the formation of epoxy amines. Subsequent nucleophilic attack of the epoxide by the ylide yields a bis-anion, which upon a 5-exo-tet ring closure yields the desired pyrrolidine, thus completing the relay of the 3-membered the 5-membered nitrogen containing ring system. This process takes place with complete transfer of stereochemical fidelity, and can be applied to sterically hindered aziridinols.

摘要:Wide range of polyurethane products, e.g., cellular, dense elastomer, and integral skin microcellular products, obtained by the reaction of (a) a polyisocyanate compound, (b) a polyol, (c) optionally a chain extender and/or blowing agent with/without other known additives, (d) in the presence of a nonhydroxyl flow modifier characterized by carbon and hydrogen atoms, at least one and, generally, a plurality of oxyalkylene groups, and at least one urethane, $(1,5)omicronp. Several of the polyurethane products exhibit unique properties, e.g., foamed articles with capability to conduct static electricity, soft elastomers characterized by improved coefficient of friction, etc. Several classes of the flow modifiers are novel per se. The polyurethane products can be synthesized via the one shot or prepolymer process. Multipackage systems, in particular, two and three component systems are useful in molding operations, e.g., manufacture of shoe soles.
