PROBLEM TO BE SOLVED: To provide a short-step, highly stereoselective method for producing sanshools, and an alkyne derivative that is an intermediate useful for the method.SOLUTION: The alkyne derivative is represented by general formula (I), wherein Arepresents a halogen atom; and R represents a hydrogen atom, hydroxy or methyl. The method for producing sanshools uses this alkyne derivative, and comprises a step of cross-coupling reacting the alkyne derivative with a boronic acid derivative.

Unsaturated isobutylamide synthons are employed to make seven natural amides.The (Z)-selectivity of the Wittig reaction towards the newly formed olefinic bond in the seven examples is estimated by 13Cmr.
