Simple syntheses of phosphoric (4) and carboxylic (6) acid anhydrides have been elaborated by means of solid potassium carbonate in phase-transfer catalytic acylation. Behavior of various acid chlorides, phosphoric (1), sulfonic (2), and carboxylic (8), have also been studied toward potassium carbonate in the presence of lipophilic quaternary ammonium salt.

Partial degradation reactions of the macrocyclic lactam-lacton antibiotic myxovirescin A1 (1) yield the key building blocks 2 and 26.From these myxovirescin analoga are reconstituted with various alkyl groups at position C-2 with R and S configuration.Furthermore a ring-contracted (24) and a ring-enlarged (29) macrocycle are synthesized.The growth of E. coli is best inhibited by the natural myxovirescin A1 with a (2S) propyl substitution whilst 24 and 29 do not inhibit the growth of E. coli at all.
