Novel chiral C2-symmetric bisimidazole-N-oxides as promising organocatalysts for enantioselective allylation of aromatic aldehydes
A series of new, chiral Lewis bases containing imidazole-N-oxide moiety were tested for purposes of asymmetric catalysis. Bisimidazole-N-oxides derived from (1R,2R)- and (1S,2S)-trans-1,2-diaminocyclohexane were used as catalysts in the allylation reaction of aromatic aldehydes with allyltrichlorosilane, which yielded homoallyl alcohols in good yields and with enantioselectivity up to 80% ee. Screening of catalysts revealed that the type of substituents and their location in imidazole ring has a crucial influence on enantioselectivity of the addition process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: (1S,2S)-Cyclohexane-1,2-diamine, you can also check out more blogs about21436-03-3
