Optically active allenyltitanium [cf. (III)], generated from propargyl alcohol derivatives in solution, undergoes regioselective hydrolysis and halogenolysis to give the alkyne (IV) and the chloride (V) with excellent degree of chiral transfer. This approach is also successfully applied to the synth
