Synthesis of pinacol esters of 2,3-alkadienylboronic acid via the copper(I) mediated coupling reaction of Knochel's (dialkoxyboryl)methylzinc reagents with propargylic tosylates

, p. C4 - C8 (1994)
The reaction of propargyl tosylates (1) with (dialkoxyboryl)methylcopper(I) reagents, prepared in situ from Knochel's (dialkoxyboryl)methylzinc iodide (2) and CuCN*2LiCl, produced 2,3-alkadienylboronates (3) in moderate yields. The reaction proceeded regi
Expanded scope in ethylene-alkyne cross-metathesis: coordinating heteroatom functionality at the propargylic position.

The Grubbs 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene-substituted ruthenium complex 1 catalyzed ethylene-alkyne cross-metathesis and was shown to tolerate free hydroxyl groups and coordinating functionality at the propargylic and homopropargylic position
