A concise and practical enantioselective synthesis of (+)-strictifolione has been achieved in high diastereomeric excess using Jacobsen's hydrolytic kinetic resolution, proline-catalyzed sequential alpha-aminoxylation an...
Microwave-assisted synthesis represents a new methodology to obtain calix[6]arene building blocks. The synthesis of compounds 1 and 2 is described. These compounds are A, D-m-xylylenedioxy-bridged calix[6]arenes in cone ...
An efficient method for the preparation of the synthetically attractive perfluoroalkyl ketones through the reaction of readily available alkenoates, alkynoates, or regular carboxylic esters with perfluoroalkyl Grignard r...
Oxone has been found to be a highly efficient reagent for the introduction of a hydroxy group at the a position of a variety of beta-dicarbonyl compounds in the homogeneous solvent mixture of water and 1,4-dioxane at 60 ...
Direct alkylation of indoles with a wide variety of tertiary propargylic alcohols under Bronsted acid catalysis conditions has been studied. A general and environmentally friendly method for the synthesis of 3-propargyla...
