Abstract

(2R,6S,8R)-2,8-Dimethyl-1,7-dioxaspiro[5.5]undecane (1a) and its enantiomer 1b, have been synthesized by Wittig’s methodology using the ylide from acetone-1,3-bis(triphenylphosphonium) chloride and the appropriately protected aldehydes from chiral 1,3-butanediols. The latter are prepared by a chemoenzymatic resolution procedure.
