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.

Polyketides belong to the most valuable natural products, including diverse bioactive compounds, such as antibiotics, anticancer drugs, antifungal agents, immunosuppressants and others. Their structures are assembled by polyketide synthases (PKSs). Modular PKSs are composed of modules, which involve sets of

Efficient syntheses of N-acetyl thienamycin and epithienamycin A in their readily deprotected form are reported where three contiguous stereocenters are established in a single catalytic asymmetric azetidinone-forming reaction. These examples are a template for synthesizing C-5/C-6 cis or trans carbapenems
