General description

N-Acetylcysteamine, also known as N-(2-Mercaptoethyl) acetamide, is a derivative of cysteamine, that is commonly used as a building block for the synthesis of alkylated thiol and thioesters via esterification.

Application

N-Acetylcysteamine can be used as a building block to synthesize:
  • N







  • -acetylcysteamine (SNAC) thioesters by reacting with various acid derivatives in the presence of 1,1′-carbonyldiimidazole (CDI).      
  • Thieno[2,3-c]pyrrole derivatives via three-component reaction of 2-acetyl-3-thiophenecarboxaldehyde and various amines.
  •  Carbapenems, a class of beta-lactam antibiotic agents.
