The zinc–mediated aqueous Barbier–Grignard reaction of cyclic allylic bromide substrates with various aldehydes and ketones to afford homoallylic alcohols was investigated. Aromatic aldehydes and ketones afforded adducts in good yields (66–90%) and with good diastereoselectivities. Non–aromatic aldehydes also reacted well under these conditions, but only poor yields were obtained with non–aromatic
研究了环状烯丙基溴底物与各种醛和酮的锌介导的巴比耶-格利雅水溶液反应,以提供高烯丙醇。芳香醛和酮以良好的收率(66-90%)提供加合物,并具有良好的非对映选择性。在这些条件下,非芳香醛也能很好地反应,但非芳香酮的收率很低。当研究一些取代的环状烯丙基溴时,区域选择性很高。
