Abstract: Allylation of bulky-substituted aromatic aldehydes with allyltrichlorosilanes were catalyzed by axial biscarboline N,N’-dioxide esters with high enantioselectivities up to 92% e.e. for 1-(4-chlorophenyl)-9-methyl-9H-pyrido[3,4-b]indole-3-carbaldehyde and 90% e.e. for 1-(3-methoxyphenyl)-9-methyl-9H-pyrido[3,4-b]indole-3-carbaldehyde, respectively. Total 22 aldehydes were tested with… read more here.
