We developed a simple, efficient, and selective method for preparing organic carbamates and carbonates using a catalytic amount of indium. A wide range of carbamates and carbonates were synthesized… (More)
We have developed a one-pot process for preparing sulfonyl azides by treating sulfonic acids with trichloroacetonitrile, triphenylphosphine, and sodium azide at room temperature. A wide range of… (More)
Abstract We developed a mild and convenient trifluoroacetylation process for amines using a combination of trichloroacetonitrile and triphenylphosphine. The reaction that we designed is applicable to… (More)
A wide variety of aliphatic and aromatic amines is transformed to formamides in good to excellent yields.
A facile and efficient method for synthesizing sulfon-amides was developed using a catalytic amount of indium metal. A wide range of sulfonamides were synthesized in excellent yields using the new… (More)
The title compounds are synthesized using one-pot, three-component Traube—Schwarz reaction with various aldehydes in presence of a zinc catalyst.
An efficient and chemoselective method for the formylation of amines is presented which uses activated zinc as a catalyst.
A variety of carboxylic acids is converted into the corresponding acyl fluoride using an optimized one-pot two-step sequence which involves the in situ formation of carboxylic acid chlorides.
Excellent yields and enantioselectivities are obtained in the asymmetric allylation of N-benzoylhydrazones using cationic quinidine- or quinine-derived organocatalysts (I)/(II).
