资源简介:
Homoallylation of aldehydes with isoprene and triethylborane catalyzed by Ni(acac)2 gave hydroxyalkenes in good yield with excellent regio- and stereoselectivity. Cross metathesis of the hydroxyalkenes with methyl acrylate using second-generation Grubbs catalyst and copper(I) iodide afforded α,β-unsaturated esters, which underwent cyclization in the presence of DBU to produce tetrahydrofurans with the correct relative configuration for the C1−C9 fragment of amphidinolides C, C2, and F.
