Stereoselective Synthesis of Alcohols, XLVIII[1] 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 sterocenter at C‐6, and two stereoselective allylboration reactions to generate the stereocenters at C‐2, C‐3, C‐4, and C‐5.
