Synthesis and Antimicrobial Activity of N,N-Disubstituted 3-Allyloxy-1-amino-2-propanethiols
摘要:
3-Allyloxy-1,2-epithiopropane was synthesized; its treatment with amines yielded N,N-disubstituted 3-allyloxy-1-amino-2-propanethiols, which were tested for antimicrobial activity.

Herein we shed light on the mechanism of the reaction of epoxides with ammonium thiocyanate to give the corresponding thiiranes in water, and we present a computational mechanistic model for this highly useful reaction.
Bis(trimethylsilyl)selenide in the Selective Synthesis of β-Hydroxy, β-Mercapto, and β-Amino Diorganyl Diselenides and Selenides Through Ring Opening of Strained Heterocycles
dialkyl diselenides and selenides is described through reaction of bis(trimethylsilyl)selenide with epoxides, thiiranes, and aziridines catalyzed by tetrabutylammonium fluoride. Selective formation of a wide variety of β-hydroxy, β-mercapto, and β-amino diselenides and selenides is achieved by controlling the reaction conditions in the regioselective attack of the silylselenide onto the ring-strained
Micellar media are introduced for the efficient ring opening of epoxides with sodium salts of nucleophiles such as CNâ, N3â, NO3â, NO2â, SCNâ, Brâ and Clâ, catalyzed with Ce(OTf)4. This method is an efficient procedure for the synthesis of different β-substituted alcohols under mild reaction conditions. The reaction with SCNâ is an easy procedure for the high yielding preparation of epoxy sulfides.

Efficientring opening of epoxides under mild conditions is reported. Potassium dodecatungstocobaltate(III) trihydrate was used as an efficient catalyst for the alcoholysis and acetolysis of epoxides. Conversion of epoxides to thiiranes was also performed efficiently in the presence of this catalyst.

Epoxides react smoothly with potassium thiocyanate in the presence of 5 mol% of indium tribromide under mild and convenient reaction conditions to afford the corresponding thiiranes in high yields. This method is compatible with a wide range of protecting groups and functional groups such as alkenes, alkynes, esters, THP, TBDMS, and PMB ethers present in the molecule.
