Suzuki–Miyaura coupling of nonbenzylic α‐(acylamino)alkylboron compounds with aryl halides is established. A Pd/PCy2Ph catalyst promotes the reaction efficiently at 145 °C. The reaction of enantioenriched α‐(acylamino)alkylboron compounds affords chiral 1‐arylalkylamides in high enantiospecificity and inversion of configuration.
Provided herein are compounds, such as a compound of Formula (I), as described herein, or a pharmaceutically acceptable salt thereof, that are immunoproteasome (such as LMP2 and LMP7) inhibitors. The compounds described herein can be useful for the treatment of diseases treatable by inhibition of immunoproteasomes. Also provided herein are pharmaceutical compositions containing such compounds and processes for preparing such compounds.

First sonochemical, simple and solvent-free synthesis of chiral <i>tert</i>-butanesulfinimines using silica supported <i>p</i>-toluenesulfonic acid
Abstract A solvent-free, versatile procedure has been developed for the effective synthesis of tert-butanesulfinylimines of a variety of aldehydes using chiral tert-butanesulfinamides under green, sonochemical conditions. This method utilizes silica supported p-toluenesulfonic acid (pTSA·SiO2) as an efficient, safer and inexpensive catalystunder aerobic conditions. The practicable simplicity, easy

environmentally friendly, and very efficient procedure for the synthesis of opticallypureN-(tert-butylsulfinyl)imines has been developed with microwave-promoted condensation of aldehydes and ketones using (R)-2-methylpropane-2-sulfinamide in the presence of Ti(OEt)4, under solvent-free conditions. This procedure allows for the preparation of a variety of sulfinyl aldimines with excellent yields and purities
