2-addition reaction of 2,3-allenoates with allyl magnesiumchloride at room temperature in the absence of any transition metal catalyst provides an efficient method for the synthesis of tertiary alpha-allenols. The optically active allenol could be prepared from the reaction of the optically active 2,3-allenoate without obvious racemization of the axial chirality. Under different reaction conditions
