Tributylstannyl

The 1,3-isomerization of the a-hydroxy allylstannane, (/ )-( )-1-tributylstannyl-2-heptenol (see p 402), to the silyloxy allylstannane 5 which follows an anti-pathway (for assignment, see p 445)75. [Pg.422]

The arylation of the 1-tributylstannyl glycal 717 offers a synthetic route to chaetiacandin[585,586]. The Pd-catalyzed reactions of the 3-stannylcyclobute-nedione 718 with iodobenzene, and benzoyl chloride[587], and alkenylation with alkenyl(phenyl)iodonium triflates proceed smoothly by the co-catalysis by Cul[588,589],...
