Stereoselective Synthesis of Alcohols, XLVIII - Linear Synthesis of (9S)-Dihydro-erythronolide A

Starting from building block 3 comprising the C-7 to C-15 segment of erythronolide A, a linear synthesis of erythronolide A has been achieved.Key steps were a Sharpless-epoxidation to set up the stereocenter at C-6, and two stereoselective allylboration r
