Metal and Oxidant Free Construction of Substituted- and/or Polycyclic Indoles: A Useful Alternative to Bischler and Related Syntheses

A wide range of substituted indoles or polycyclic derivatives containing the indole core are easily accessible by acidic treatment of aromatic amines and 1,2-diaza-1,3-dienes. Unlike the related indole-Bischler synthesis, the regioselectivity of the method here reported is unique and predictable, the yields are generally good and also electron withdrawing substituted indoles are smoothly recovered.

Ru-Catalyzed Switchable N-Hydroxyethylation and N-Acetonylation with Crude Glycerol

Highly efficient Ru-catalyzed selective C?C or C?O bond cleavage of polyols (e.g., crude glycerol) for N-hydroxyethylation or N-acetonylation of amines was achieved through the hydrogen-borrowing approach. A variety of amines were transformed to the desired amino alcohols/ketones in moderate-to-excellent yields, opening up new avenues for generation of oxygenated pharmaceuticals and fine chemicals from renewable raw materials. The use of new redox-active catalysts containing bisphosphine/thienylmethylamine ligands allows this hydrogen-borrowing system to be operated selectively under both basic and acidic conditions.

Direct hydroxyethylation of amines by carbohydrates: Via ruthenium catalysis

An efficient and halogen-free catalytic methodology for the synthesis of β-amino alcohols from aromatic amines and biomass-derived carbohydrates is demonstrated for the first time. The activation of C5/C6 sugars by a ruthenium catalyst selectively generates the C2 alkylating reagent glycolaldehyde. The transformation involves metal-catalyzed hydrogen borrowing for the reduction of the imine intermediate. A series of arylamines bearing various substituents were successfully transformed into the desired products in good to excellent yields.

Preparation method of N-acetonyl amine compound

The invention discloses a preparation method of an N-acetonyl amine compound. The method comprises the following steps that an amine compound and glycerin are used as reaction raw materials, and in the presence of a composite catalyst and an alkali addition agent, in reaction mediums and at the reaction temperature of 80-180 DEG C, a reaction is performed for 2-48 hours in a sealed reactor so that the N-acetonyl amine compound is obtained. The method disclosed by the invention is simple, reaction conditions are mild, target products can be obtained at a low cost and at a high yield, and the used catalyst has high catalytic activity and is easy to separate and repeatedly use in a reaction system; besides, the whole process is environment-friendly, and the utilization of by-products namely the glycerin of biologic diesel oil is promoted.

Bioconjugatable azo-based dark-quencher dyes: Synthesis and application to protease-activatable far-red fluorescent probes

We describe the efficient synthesis and one-step derivatization of novel, nonfluorescent azo dyes based on the Black Hole Quencher-3 (BHQ-3) scaffold. These dyes were equipped with various reactive and/or bioconjugatable groups (azido, α-iodoacetyl, keton

A NEW SYNTHESIS OF 3-SUBSTITUTED INDOLINES AND INDOLES

3-Phenyl- and 3-alkyl-3-hydroxyindolines were synthesized by intramolecular Barbier reaction of phenyl and alkyl N-(2-iodophenyl)-N-methylaminomethyl ketones with n-BuLi, which were easily prepared from N-methyl-2-iodoaniline and bromomethyl ketones.The treatment of the indolines with acid gave the corresponding indoles in quantitative yields.
