将由磺酰化氨基酸和长链的含甲氧基官能团的胺制备的(S)-N-(4-甲氧基苯乙基)-3-苯基-2-(对甲基苯磺酰胺)丙酰胺(1d)手性配体用于催化二乙基锌与系列芳香醛对映选择性加成反应. 15 mol%该催化剂能够对含有吸电子基团、供电子基团及不同位阻的芳香醛均有较好的效果, 能够在比较温和的条件下获得高达87% ee 和中等程度的产率.

Enantioselective addition of diethylzinc to a series of aromatic aldehydes was developed by chiral ligand (S)-N-(4-methoxyphenethyl)-3-phenyl-2-(tosylamino)propanamide (1d), which was derivatived from a modular amino acids and long chain amine containg OMe. The catalytic system employing 15 mol% of 1d without using titanium complex was found to promote the addition of diethylzinc (ZnEt2) to a wide range of aromatic aldehydes with electron-donating and electron- withdrawing substituents, giving up to 87% ee of the corresponding secondary alcohol under mild conditions.

Key words: addition reaction, aldehyde, amino acid, phenylethanamine, ditheylzinc
