Stereoselective synthesis of chiral spiroacetals starting from enol-ester 1, derived from D-manno lactone, is described. The strategy involves 1,4-addition of a variety of alcohols to 1 in the presence of NBS to give αbromo acetals, which undergo a regio-and stereoselective radical cyclisation to gi
