Abstract
Abstract Sterically congested trans -4,5-di- tert -butyl-2-imidazolidinone (DTBIm) and trans -4,5-di-(1-adamantyl)-2-imidazolidinone (DAIm), which are prepared from the parent 1,3-dihydro-2-imidazolone, undergo an unusual N -acylation reaction with acyl chlorides in the presence of organic amines to give the 3-oxoacyl derivatives.
