Compound I is a densely functionalized iminohydantoin that possesses a quaternary stereocenter and is under development as an HIV protease inhibitor. Key challenges that are discussed include the preparation of a neopentyl Grignard reagent via magnesium insertion, development of a one-pot Curtius reaction that generated a volatile isocyanate and was trapped with an alc., and removal of a CBz protecting group to isolate a succinate salt. This study describes process development efforts that enabled the first scale-up of I. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Computed Properties of C4H12ClN).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Computed Properties of C4H12ClN
