Abstract

A domino 1,4-addition/alkyne carbozincation sequence based on a radical zinc-atom transfer process is disclosed. Two efficient multicomponent approaches to 3-alkylidenetetrahydrofurans from β-(propargyloxy)enoates bearing pendant alkynes (including ynamides) have been established: one involving the direct addition of dialkylzincs, and the second involving the dimethylzinc-mediated addition of alkyl iodides. Both sequences utilize the stereoselective formation of intermediate alkylidenezincs well suited for in situ functionalization with electrophiles.

Reductive zincation of a vinyl radical has also been suggested to account for the formation of allenoates following zinc-mediated radical addition to propiolates, see ref. 17.

When CH2Cl2 was used as solvent, the Z/E ratio of product 5ha might not fully represent the diastereoselectivity of the zinc-atom transfer since in addition to these two diastereomers, a third tetrahydrofuran side product having incorporated a butyl residue was detected (∼20% yield in the crude) but could not be fully identified. In any case the diastereoselectivity of the reaction between 1h and Bu2Zn in CH2Cl2 should at best be mediocre.
