Solvent-free synthesis of monoacylaminals from the reaction of amides and aminals as precursors in carbinolamide synthesis
摘要:
A solvent-free method of generating monoacylaminals by heating the amide and aminal starting materials in the presence of one another has been developed. Yields were generally between 45% and 65% with the monoacylaminal being isolated, needing no further purification after drying under high vacuum. (C) 2010 Elsevier Ltd. All rights reserved.

A novel silver-catalyzed nucleophilicsubstitution of aminals with ethyl diazoacetate producing β-amino-α-diazoesters has been developed. A series of aminals with different amino moieties and substituents were successfully incorporated in this reaction, which delivered a wide range of β-amino-α-diazocarbonyl compounds in the presence of a lower catalyst loading in 2 hours.
