A Regio-and Stereoselective Synthesis of β-Amino Alcohols

Abstract The regio-and stereoselective ring opening of epoxide with aromatic amines catalyzed by samarium trichloride and the enantioselective ring opening of cyclohexene oxide with aniline catalyzed by lanthanide complexes were studied.

Reaction of Propargyl Bromide with Aldehydes in the Presence of Metallic Tin. Synthesis of Homopropargylalcohols and Homoallenylalcohols

Abstract In the presence of water, metallic tin and propargyl bromide reacted smoothly with aldehydes to give the corresponding homopropargyl alcohols (a) and homoallenyl alcohols (b). High Chemospecifity to bifounctional carbonyl compounds containing -OH, -X and -NO2 etc. was obtained.

The Novel Reduction Systems: NaBH4-SbCl3 OR NaBH4-BiCl3 for Conversion of Nitroarenes to Primary Amines

Abstract Nitroarenes can be conveniently reduced to primary amines in good to excellent yields by sodium borohydride in the presence of bismuth chloride or antimony chloride.

Manganese(III) acetate-mediated free radical reactions of [60]fullerene with β-dicarbonyl compounds

[60]Fullerene reacted with various beta-dicarbonyl compounds in the presence of Mn(OAc)3*2H2O to generate dihydrofuran-fused [60]fullerene derivatives or 1,4-bisadducts. Dihydrofuran-fused [60]fullerene derivatives 2 could be formed by treatment of alpha-unsubstituted beta-diketones 1a-e or beta-ketoesters 1f and 1g with [60]fullerene in refluxing chlorobenzene in the presence of Mn(III). Solvent-participated unsymmetrical 1,4-bisadducts 3 were obtained through the reaction of [60]fullerene with dimethyl malonate 1h or alpha-substituted beta-dicarbonyl compounds 1i-1n in toluene. A possible reaction mechanism for the formation of different fullerene derivatives is proposed.

A New Approach for the Synthesis of α-Methylene-γ-Butyrolactones from α-Bromomethyl Acrylic Acids (or Esters)

Abstract This paper reports that a new approach for the synthesis of α-methylene-γ-butyrolactones from the reaction of α-bromomethyl acrylic acid (or ester), powdered tin and carbonyl compounds in one pot with excellent to good yields.

Barbier-Type Allylation of Aldehydes and Ketones with Metallic Lead in Aqueous Media

Abstract Homoallylic alcohols can be obtained from allylation of aldehydes and ketones with allyl bromide promoted by metallic lead. These reactions can be carried out smoothly in aqueous media.

SYNTHESIS OF N-ARYLHYDROXYLAMINES BY ANTIMONY-CATALYZED REDUCTION OF NITROARENES

Abstract Metallic antimony catalyzes the reduction of aromatic nitro compounds to the corresponding N-arylhydroxylamines in good yields with NaBH4 under mild conditions. The azoxybenzenes from autoxidation of N-arylhydroxylamines were also obtained in basic conditions.

Photoinduced Reaction of [60]Fullerene with Tertiary Amines: Synthesis of [60]Fulleropyrrolidines

Abstract [60]Fulleropyrrolidine derivatives were prepared from the photoinduced reaction of [60]fullerene and tertiary amines.

A Facile Synthesis of 1,3,5-Triaryl Benzenes from Acetophenone Diethyl Ketals in the Presence of Acetyl Chloride and SmCl3

Abstract Samarium trichloride, SmCl3, has been found to be an efficient catalyst for the synthesis of 1,3,5-triaryl benzenes from acetophenone diethyl ketals in the presence of acetyl chloride under solvent of pentane and mild conditions.

A Facile Method for the Transformation of Acetals and Ketals to Aldehydes and Ketones

Abstract This paper reports a simple and convenient acetyl chloride-samarium trichloride system for the transformation of acetals and ketals to aldehydes and ketones
