N-Methylation of 139 with iodomethane in nitromethane afforded 2,3,4,4,6-pentamethyl-5,6-dihydro-4H-oxazinium iodide 140. Deprotonation of 140 with sodium hydride resulted in formation of the cyclic ketene-N,O-acetal derivative tetrahydro-1,3-oxazine 141 (Scheme 21) <2006JCO262>. Sign in...
In the course of our work on umpolung of 卤,-ethylenic ketones and aldehydes1, the use of thioacetalised -ketophosphonium salts and ylids led us to investigate the hydrolysis of 1,3-dithianes. Among the known methods of removal of thioacetal protecting groups2, the one using cerium (IV...
The presence of acid or base catalysts can greatly enhance the reactivity and rate of hydrolysis for certain compounds. Acid-catalyzed hydrolysis is common for substances such as amides and acetals, while base-catalyzed hydrolysis is observed in reactions involving esters and carboxylic acids. ...
