Conformationally and configurationally homogeneous 2α-R1-4α-R2-cis-1-thiadecalins with an equatorial orientation of the substituents attached to the C(2) and C(4) atoms were isolated as the final reduction products in the catalytic hydrogenation on palladium of 2-R1-4-R2-4H(6H)-cyclohexa[b]thiopyrans, cis-3-R1-5-R2-2-thiabicyclo[4.4.0]-δ1,6-decenes, and 2-R1-4-R2-cyclohexa[b]thiopyrylium tetrafluoroborates and trifluoroacetates. cis-3-R1-5-R2-2-Thiabicyclo[4.4.0]-δ1,6-decenes were obtained as… CONTINUE READING
