The total synthesis of macrosphelide M is described. The key steps include the preparation of the acid and alcohol fragments from diacetone glucose and (S)-malic acid, respectively, followed by Yamaguchi esterification and macrocyclization of the tris-olefin by ring-closing metathesis. Finally, one-pot deprotection of the PMB and TBS groups with TiCl4 results in the target. The C-3/C-4 stereocenters of diacetone glucose are used for the introduction of four stereocenters, whereas the fifth stereocenter is realized from (S)-malic acid. The total synthesis of macrosphelide M was achieved from diacetone glucose and (S)-malic acid. The key steps include Yamaguchi esterification and macrocyclization of the tris-olefin by the second-generation Grubbs catalyst.
