Abstract

Stereoselective synthetic efforts for erythronolide A seco acid are reviewed from the first discovery of erythromycin A in 1952 up to the end of 1990. The synthetic strategies for construction of ten asymmetric centers embedded in an aglycone of erythramycin A have mostly been realized by the stereoselective preparation of the key fragments followed by coupling them. The synthetic methods employed for the key fragments can be classified into three categorie; a carbohydrate approach, a cyclic approach and an acyclic approach. The coupling has largely been reduced to practice by either aldol-type additions or Wittig olefinations of the key fragments.
