A chiral base route from a meso cyclohexene oxide to an allylic alcohol provides key intermediates for the synthesis of cyclic polyols. A Mitsunobu approach and an Overman rearrangement approach transform allylic alcohols into some aminodeoxyconduritols (95% ee). Elaboration of a chiral enone (89% ee) via (i) α-hydroxylation and (ii) stereoselective reduction completes a high yielding synthesis of
