Successive treatment of propargylic carbonates or phosphates with a Ti(O-i-Pr)4/2i-PrMgC1 reagent and dialkyl azodicarboxylates gave ct-hydrazinoalkynes in good yields. The reaction, which proceeded with up to 86% chiral transfer, thus has opened up a new route to optically active ct-hydrazinoalkyne
