Fourteen-membered cytotoxicmacrolides 1 and 2 were synthesized from alcohol 10 in 15 steps utilizing stereospecific Pd(II)-catalyzed cyclization of ζ-hydroxy chiral allylic alcohol 7. Aspergillides A and B were isolated from marine fungus, and their structures were proposed as 1 and 2, respectively. The synthetic 1 was not matched with aspergillide A but matched with aspergillideB. The chiral center
