Conformationally and configurationally homogenous 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 produc

The structure of aryl-substituted cis-1-thiadecalins formed together with 5,6-tetramethylenethiopyrylium salts in disproportionation reactions of condensed 4H-, 6H-thiopyrans and dihydrothiopyrans with CF3COOH, as well as in the ionic reduction of the latter by the ion pair trifluoroacetic acid-triethylsilane, was studied.It was shown that the reduction proceeds stereospecifically with the formation of configurationally and conformationally homogeneous aryl-cis-1-thiadecalins possessing 2α-R1- and 2α-R1-4α-R2-configurations.The configurational and conformational assignments were made by the 13C NMR method.
REACTIONS OF "SEMICYCLIC" 1,5-DIKETONES WITH HYDROGEN SULFIDE AND TRIFLUOROACETIC ACID

, p. 170 - 173 (2007/10/02)
The reactions of known and new "semicyclic" 1,5-diketones with hydrogen sulfide and with trifluoroacetic acid were studied.It was shown that under the investigated conditions both 1-aryl- and 1,3-diaryl-substituted diketones form 3R-5R-2-thiabicycloalkane
