Transition-Metal-Promoted Oxidative Cyclization To Give 1,2,4-Trisubstituted Carbazole Scaffolds
PublicationHerein, we describe the synthesis of a 1,2,4-trisubstituted carbazole core from 5-(1H-indol-3-yl)-3-oxopentanoic acid esters or amides. For oxidative cyclization, we tested two different approaches. First, we used manganese triacetate as a conventional moderate oxidizer to ensure the radical course of the reaction. Second, we examined the use of a more complex oxidizing agent I2/Me(OTf)3. In both cases, formation of a fused-ring...

Practical Method for the Preparation of 2,2-Dimethyl-5- {aryl[(hetero)aryl]methyl}-1,3-dioxane-4,6-diones: Synthesis and Mechanistic Study
PublicationAn efficient practical synthetic procedure has been developed for the synthesis of 2,2-dimethyl-5-{aryl[(hetero)aryl]methyl}- 1,3-dioxane-4,6-diones through Friedel–Crafts alkylation. The scope and limitation of the reaction of 2,2-dimethyl-5-arylidene-1,3-dioxane- 4,6-diones with π-excess aromatic systems have been delineated.

One-Step Synthesis of b-Lactams with Retro-Amide Side Chain
PublicationAbstract: A one pot synthesis for preparation of 1,4-disubstituted-2-oxo-azetidine-3-carboxylic acid amides was developed. 5-(α-N-substituted-amino-α'-hydroxy)methylene Meldrum's acids act as a source of ketenes that react with aldimines in boiling toluene to give b-lactams with retro-amid side chain.

Novel and Efficient Methods for the Synthesis of Symmetrical Trisulfides
PublicationWe have developed a convenient methods for the synthesis of symmetrical trisulfides under mild conditions in very good yields. The described methods are based on the straightforward preparation of 5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinane-2-disulfanyl derivatives from readily available 5,5-dimethyl-2-sulfanyl-2-thioxo-1,3,2-dioxaphosphorinane or bis(5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl) disulfide. The symmetrical...

A versatile and convenient preparation of unsymmetrical diaryl disulfides
PublicationWe have developed a convenient method for the synthesis of unsymmetrical diaryl disulfides under mild conditions in excellent yields. The described method is based on the straightforward preparation of 5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinane-2-sulfenyl bromide from readily available 5,5-dimethyl-2-thiolo-2-thioxo-1,3,2-dioxaphosphorinane or bis(5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl) disulfide. The unsymmetrical...

S-thioacyldithiophosphates in the synthesis of thiohydroxamic acids and O-thioacylhydroxylamines
PublicationDitiofosforany tioacylu to trwałe, łatwo osiągalne z kwasów karboksylowych środki tioacylujące. Z powodu ich niskiej reaktywności wobec nukleofili tlenowych i wysokiej wobec nukleofili azotowych znalazły zastosowanie w syntezie kwasów tiohydroksamowych bezpośrednio z hydroksyloamin z niechronioną grupą hydroksylową. W przypadku dużej zawady przestrzennej można otrzymać O-tioacylohydroksyloaminy.
