Syntheses of substituted 6-hydroxyhexenoic acids and related tetrahydrofuran systems by metallocene-template directed 1,4-selective coupling of 1,3-butadiene with carbonyl compounds

, p. 212 - 222 (2007/10/02)
Butadiene is 1,4-selectively coupled with a metal carbonyl and a ketone at the bis(η-cyclopentadienyl)zirconium template to yield the nine-membered metallacyclic products 3. Subsequent hydrolysis under oxidative conditions (pyridine N-oxide) gives the cor
GENERATION OF DIENONE AND TRIENONE DIANION DERIVATIVES; DOUBLE DEPROTONATION AS A ROUTE TO LUMO-FILLED ?-SYSTEMS

Conjugated unsaturated carbonyl compounds and their analogues 1 are a1,3,5...-reagents.An umpolung of this intrinsic reactivity can be achieved by generation of the dianions 2, LUMO filled ?-systems, from hydrogenated precursors, see schemes 1
