Application

2,4,6-Trichlorobenzoyl chloride may be used in the preparation of:
  • γ-lactone and δ-lactone
  • aliphatic aromatic anhydrides, required for the synthesis of amphiphilic hyaluronan
  • mixed anhydride, required for the synthesis of angelate esters
  • synthesis of both spongistatin 1 and spongistatin 2
  • large-ring lactones in high yields.

Alkaline hydrolysis of 4-hydroxy- or/and 5-hydroxy-(2E)-alkenoate followed by acid treatment gave the corresponding (2E)-alkenoic acids which were subjected to lactone formation reaction without further purification. The crude acids were treated with 2,4,6-trichlorobenzoyl chloride in pyridine to afford γ-lactone or δ-lactone

The total synthesis of spongistatin 1 (1) and spongistatin 2 (2) has been achieved through an advanced-stage intermediate. The synthesis is highlighted by a highly convergent assembly of the four key fragments (the C1-C15 AB fragment 2, the C16-C28 CD

The present work describes a novel and efficient method of synthesis of amphiphilic hyaluronan (HA) by esterification with alkyl fatty acids. These derivatives were synthesized under mild aqueous and well controlled conditions using mixed aliphatic aromatic anhydrides. These anhydrides characterized
