Enantioselective synthesis of natural polyoxygenated cyclohexanes and cyclohexenes from [(p-tolylsulfinyl)methyl]-p-quinols

Exploitation of the β-hydroxysulfoxide fragment present in a number of enantiomerically pure (SR)and (SS)-[(p-tolylsulfinyl)methyl]-pquinols allowed chemo- and stereocontrolled conjugate additions of different organoaluminium reagents to the cyclohexadien

Enantioselective synthesis of (+)- and (-)-dihydroepiepoformin and (+)-epiepoformin

(Chemical Equation Presented) The enantioselective synthesis of both enantiomers of dihydroepiepoformin (1) and (+)-epiepoformin (2) was achieved from (p-tolylsulfinyl)-methyl-p-quinols (SR)- or (SS)-3 and (4R,SR)-4, respectively. Key features include the

Studies of Diastereoselectivity in Conjugate Addition of Organoaluminum Reagents to (R)-[(p-Tolylsulfinyl)methyl]quinols and Derivatives

(R)-4-Hydroxy-4-[p-tolylsulfinyl)methyl]-2,5-cyclohexadienones 1-3, and 6 reacted with organoaluminum derivatives from the pro-R conjugated position in a highly π-facial diastereoselective manner directed by the C-4 OH. A similar facial diastereoselectivity arose from reactions with 3-alkylsubstituted analogues 4 and 5 and 5-alkyl-4-hydroxy-4-[(p-tolylsuIfinyl)methyl]-2-cyclohexenones 10a,b. Semiempirical calculations (AM1 model) provide data on transition-state energies for additions in full agreement with the experimental results.
