Endo-selective enyne ring-closing metathesis promoted by stereogenic-at-W mono-pyrrolide complexes.

ABSTRACT: The utility of W-alkylidene complexes for enyne ring-closing metathesis is demonstrated in a direct comparison with Mo-based analogs. Tungsten complexes lead to less alkyne oligomerization and higher levels of endo-selectivity and enantioselectivity.
