The authors previously conducted the synthesis of macrocyclic lactones, unstaturated macrocyclic lactones and macrocyclic ketones consisting of various numbers of carbons by photocyclization. Photocyclization of precursor [A] obtained in that study was carried also in this work for the synthesis of macrocyclic oxalactone having the same scent as musk perfume. [A] was obtained in 4 steps from 1,6-hexanediol. A new method for the synthesis macrocyclic oxalactone is proposed.
