Synthesis of mono- and bis(aminomethyl)dioxanes fromN-[3-(2-chloroethoxy)-2-hydroxypropyl]sulfamates

N-Substituted aminomethyl- and 2,5-bis(aminomethyl)-1,4-dioxanes were prepared by cyclization of the corresponding potassiumN-[3-(2-chloroethoxy)-2-hydroxypropyl]sulfamates under the action of an alkaline agent followed by alcoholysis of the resulting sulfamic acids.

Synthesis of 2-substituted morpholines from dihydroxyalkylsulfamates

Abstract2-Substituted morpholines and hexahydro-1,4-oxazepines were prepared by cyclodehyration of potassium dihydroxyalkylsulfamates in concentrated sulfuric acid

Synthesis of diaminohydroxyethersvia 3-(ω-haloalkoxy)-2-hydroxypropyl sulfamates

Reactions of 3-(ω-haloalkoxy)-2-hydroxypropyl sulfamates with amines or ammonia followed by acid hydrolysis give the corresponding diaminohydroxyethers.

Synthesis ofN-3-chloroalkoxy-2-nitroxypropyl-N-alkylnitramines and their subsequent azidation

Nitration ofN-3-chloroalkoxy-2-hydroxypropyl-N-alkylsulfamates gave the correspondingN-3-chloroalkoxy-2-nitroxypropyl-N-alkylnitramines. Azidation of the latter resulted inN-azido-3-azidoalkoxypropyl-N-alkylnitramines.

THE REACTION OF SULFAMIC ACID DERIVATIVES WITH EPOXIDES 5. REACTIONS OF SULFAMATES WITH DIGLYCIDYL AND ALLYLGLYCIDYL ETHERS AND SYNTHESIS OF THE CORRE SPONDING AMINOETHERS

Reactions of diglycidyl and allylglycidyl ethers with salts of sulfamic acid followed by acidic hydrolysis of the products afforded the corresponding aminoethers. The alcoholysis of sulfamic acids with ethanol was suggested as a method for mild elimination of the sulfo group.

Synthesis of Nitroesters Based on Methylol Derivatives of Parabanic and Isocyanuric Acids

Nitroesters synthesis based on methylol derivatives of parabanic and cyanuric acids was performed. The corresponding alloxan nitroxymethyl derivative was unstable.
