A short route for the synthesis of several fenestrane derivatives is suggested based on the sequence: ( A ) etherification of μ-cobaltcarbonyl complexes of 1,6-enyn-5-ols with unsaturated alcohols, ( B ) intramolecular Khand-Pauson reaction and, ( C

Publikováno v: Tetrahedron Letters. 32:2109-2112

A short and convergent route for the synthesis of polycyclic linearly and/or angularly fused compounds is proposed based on the intramolecular alkyne-alkene-carbonyl cycloaddition with participation of the double bond bearing an electron withdrawing

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 39:94-100

An essentially new method was developed for carrying out [4 + 2]cycloaddition on the surface of Chromatographie adsorbents in the absence of solvent. This method permits the use of much milder reaction conditions and to increase the reaction's select

Convergent synthesis of the tetracyclic bcde structural fragment of retigeranic acid

Autor: V. A. Smit, A. S. Gybin, A. L. Veretenov

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 39:1736-1738

A two-step synthesis was proposed for the tetracyclic triquinane bis-enone from two monocyclic precursors. The bis-enone obtained is a structural fragment of retigeranic acid.
