Abstract

A concise stereocontrolled construction of taxane CB-ring system (C→CB) is described. The key bottom and top linking of the eight-membered B-ring were realized unprecedentedly by way of successive intermolecular aldol condensation and intramolecular aldol cyclization.

  11. Several synthetic trials launched from compound 15 have failed. In the end, we changed the benzoyl ester in compound 15 to the benzyl ether in compound 18. Compound 18 was prepared from compound 14 through a successive deprotection (Bz), protection (Bn) and aldehyde deprotection procedure.
  12. The adducts were obtained as a 9 : 1 mixture of two diastereomers, the major was assigned to be the structure indicated as 19.
