In order to find non-narcotic analgesics, 54 compounds of amino-tert-alcohol, in which a variety of substituent groups were involved at the carbon atom in 1-position and at the amino group, were synthesized by reacting various α-and β-amino acid esters with Grignard reagents. These amino acid esters were readily reacted with alkyl Grignard reagents to give the expected compounds. However, when bulky aromatic Grignard reagents were submitted to react, the reactions were found to stop at the stage of intermediate formation of the corresponding ketones.
为了寻找非麻醉性镇痛药,通过将各种α-和β-氨基酸酯与格氏试剂反应,合成了54种氨基叔醇化合物,这些化合物在1-位碳原子和氨基上涉及多种取代基团。这些氨基酸酯容易与烷基格氏试剂反应,得到预期的化合物。然而,当使用庞大的芳香族格氏试剂进行反应时,发现反应停止在相应的酮中间体形成阶段。
