1-propynyltributylstannane

One step of the total synthesis of Stemoamide reported by Jacobi and Lee, requires the use of 1-propynyltributylstannane (Scheme 1) (1). The reaction is achieved with an excellent yield.

The reaction of bistriflate (Scheme 2) with 1-propynylstannane affords to bicyclic enediyne (2).

1-propynyltributylstannane

1-Propynylstannane reacts with various Lewis acids. As an example, 1-propynyl-trichlorostannane has been prepared by reaction of SnCl4 with 1-propynylstannane (3).
