Highly Regio- and Stereoselective Hydrostannylation of Propargyl Alcohols and
Using Dibutylchlorostannane and Lithium Chloride. — γ-Unsubstituted
28- 187 Ethers
propargyl alcohols and ethers react highly regio- and stereoselective. The nature of the
ether unit plays an important role on the regioselective outcome. In contrast, γ-substituted analogues lead to mixtures of regio- and/or stereoisomers and the hydrostannylation of homologues proceeds with low to moderate stereoselectivity. The resulting vinylstannanes can be used for subsequent cross-coupling with haloarenes by a one-pot
procedure. — (MIURA*, K.; WANG, D.; HOSOMI*, A.; Synlett 2005, 3, 406-410;
