A mild protocol for the conversion of β-ketoesters and β-diketones to carboxylic acids with use of CAN in CH3CN is described. The method is compatible with a number of functional groups, and can generate carboxylic acids under neutral conditions at room temperature. The reaction is fast and general, providing an alternative method to the commonly used malonicester acid preparation. Initial mechanistic

In immunoglobulin light chain amyloidosis (AL), the unique antibody light chain (LC) protein that is secreted by monoclonal plasma cells in each patient misfolds and/or aggregates, a process leading to organ degeneration. For treating AL patients, such as those with substantial cardiac involvement who have difficulty tolerating existing chemotherapy regimens, provided herein are small molecule compounds of Formula Ia, Formula Ib, and Formula II that are kinetic stabilizers of the native dimeric structure of full-length LCs, which compounds can slow or stop the amyloidogenicity cascade at its origin.
The present invention relates to anti-RSV compounds of Formula (I) and methods for use of the compounds in the treatment and prevention of RSV infection.
