英文摘要: A new class of diamino diols was evaluated as catalytic ligands in the enantioselective borane reduction of aromatic ketones and the enantioselective thylation of aryladehydes with diethylzinc. By variation of the substitution pattern on the ketone, e.e.s of up jto 94% could be obtained by in situ borane reduction using 0.025 equiv. Of the ligand at 35℃ in THF. N,N,N',N'-Tetramethyldiamino diol and N,N'-dialkyl dialkyl diamino diol were used as promoters for the enantioselective addition of diethylzinc reagent tot the arylaldehyde, where use of 0.1 equiv. Of N,N,N'N'-tetramethyl diamino diol as catalyst in theaddition of diethylzinec to arylaldehyde achieved e.es of up to 98%.
