Enantioselective total synthesis of octalactin a using asymmetric aldol reactions and a rapid lactonization to form a medium-sized ring

Octalactin A, an antitumor agent containing an eight-memhered lactone moiety, has been stereoselectively prepared by means of enantioselective aldol reactions of selected silyl enolates with achiral aldehydes, promoted by a chiral Sn11 complex.

Asymmetric total synthesis of octalactin B using a new and rapid lactonization

A method for the synthesis of octalactin B is established via a new and quite effective mixed-anhydride lactonization for the synthesis of an eight-membered ring moiety using 2-methyl-6-nitrobenzoic anhydride with DMAP. Both an optically active linear pre
