## Abstract The total synthesis of (+)β9β__epi__βdictyostatin (**1b**), a diastereomer of the antimitotic marineβspongeβderived macrolide (β)βdictyostatin (**1a**), was achieved by creating 11 stereogenic centers and 4 stereogenic double bonds with a high level of stereocontrol. The yield for the 2

A rather facile stereoselective total synthesis of (9S)-9-dihydroerythronolide A starting from D-glucose was achieved via coupling of Cl-C6 and C7-Cl5 segments and subsequent macrolactonizotion. The well known macrolide antibiotic erythromycin A (1) has been an attractive synthetic target for moder

A new synthesis of (-)-rishitin (1) is reported, starting with chiral pool molecules. The crucial step is a stereo,selective vinyl radical eyelization, which gives a 10:1 ratio of 21 to 22.
