Abstract Image
Imidoyl chlorides, generated from secondary acetamides and oxalyl chloride, can be harnessed for a selective and practical deprotection sequence. Treatment of these intermediates with 2 equiv of propylene glycol and warming enables the rapid release of amine hydrochloride salts in good yields. Notably, the reaction conditions are mild enough to allow for a swift deprotection with no observed epimerization of the amino center.
