Popis

General description

Palmitic anhydride reacted with 20-methyl spirolide G to form a derivative with a retention time and spectrum identical with the metabolite, 17-O-palmitoyl-20-methyl spirolide G[1].

Application

Palmitic anhydride was used in the synthesis of water-soluble N-palmitoyl chitosan (PLCS) by coupling with swollen chitosan in dimethyl sulfoxide (DMSO)[2]. It was also used in the synthesis of N-acylphosphatidylserine[3].
