Cyclohexane derivatives
Q 0040
Organocatalytic Transformation of 1,3-Diketones into Optically Active Cyclohex— The L-proline-catalyzed domino Michael-aldol reaction of 1,3-diketones
34- 088 anones.
with methyl vinyl ketone provides cyclohexanone derivatives in a highly diastereoselective manner with good enantioselectivity (up to 80% e.e.). The reaction is also highly
regioselective when nonsymmetrical 1,3-diketones are used. The regioselectivity increases with an increase in the difference in reactivity of carbonyl groups. —
