Stereoselective Synthesis of Alcohols, XLVII - Application of Chiral Z-Pentenylboronates to the Synthesis of Erythronolide Building Blocks

The chiral pentenylboronate 3 was the key reagent in the stereoselective construction of two erythronolide building blocks 6 and 7.Addition of 3 to achiral aldehydes furnished homoallylic alcohols 21 and 26 with >98percent e.e.Addition of 3 to chiral alde
