A convenient procedure for the direct conversion of terminal alkenes into carboxylic acids
摘要:
Alkylboronic acids, readily synthesized from a variety of representative terminal alkenes via hydroboration with dibromoborane-methyl sulfide, undergo a facile oxidation with chromium trioxide in 90% aqueous acetic acid to provide carboxylic acids in 80-97% isolated yields, without rearrangement or loss of carbon.
The present invention relates to compounds of Formula (I) that are useful as inhibitors of the activity of the ubiquitin specific protease USP19. The present invention also relates to pharmaceutical compositions comprising these compounds and to methods of using these compounds in therapy.

The present application relates to novel 3-phenylpropionic acid derivatives, to processes for their preparation, to their use for the treatment and/or prevention of diseases and to their use for preparing medicaments for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of cardiovascular disorders.
The invention relates to novel lupeol-type triterpene derivatives and related compounds, and pharmaceutical compositions useful for therapeutic treatment of viral diseases and particularly HIV mediated diseases.
A facile method for synthesis of three carbon-homologated carboxylic acid by regioselective ring-opening of β-propiolactones with organocopper reagents
β-carbon-oxygen fission to give 3-substituted propionic acids. Among these three kinds of organocopper reagents, diorganocuprate, especially halomagnesium cuprate gave the highest yields of the acids, which was remarkably observed in the ring-opening of sterically hindered β-propiolactones such as β-methyl- and α,β -dimethyl-β-propiolactones and also in the reactions using the organocopper reagents with vinyl and
