The Au(I)-catalyzed intermolecular hydroalkoxylation of alkynes with allylic alcohols to provide allyl vinyl ethers that subsequently undergo Claisen rearrangement is reported. This new cascade reaction strategy facilitates the direct formation of gamma,delta-unsaturated ketones from simple starting materials in a single step.

The first catalytic alkyne hydroboration of propargyl amine boranecarbonitriles is accomplished with triazole‐AuI complexes. While the typical [L‐Au]+ species decomposes within minutes upon addition of amine boranecarbonitriles, the triazole‐modified gold catalysts (TA‐Au) remained active, and allowed the synthesis of 1,2‐BN‐cyclopentenes in one step with good to excellent yields. With good substrate

A facile strategy for the synthesis of isoxazoles has been efficaciously developed, which involves oxidation of propargylamines to the corresponding oximes followed by CuCl-mediated intramolecular cyclization of the latter. This protocol shows a straightforward way to construct a series of isoxazole cores with a wide range of functional group compatibility. Meanwhile, a gram-scale experiment and synthetic

The inventors have succeeded in developing urea, oxalamide, amide, thiourea, carbamate or ester compounds, in particular urea compounds, bearing two side groups, one of which carries a hydroxyphenyl or phenyl moiety, in particular a hydroxyphenyl moiety. These compounds have the advantage of inhibiting IRE1 RNase activity and sensitizing cancer cells, in particular GB cells, to chemotherapy. The present invention relates to urea, oxalamide, amide, thiourea, carbamate or ester compounds, in particular urea compounds containing a hydroxyphenyl or phenyl moiety, in particular a hydroxyphenyl moiety, including their pharmaceutically acceptable salts and solvates which are useful as sensitizers for chemotherapy of cancer cells, particularly in glioblastoma, and are useful as therapeutic compounds, particularly in the treatment of cancers that may be treated by alkylating agents, such as temozolomide.
