Abstract Lithium 2-p-tolylsulfinylbenzyl carbanions react with different N-substituted imines affording 1,2-diaryl ethyl (and propyl) amines with a high stereoselectivity control at both benzyllic (only dependent of the sulfur configuration) and iminic carbons. The anti:syn ratio, ranging between > 96: < 4 and < 2: > 98, dependent on the electronic density at nitrogen.
摘要 锂 2-对甲苯基亚磺酰基苄基碳负离子与不同的 N-取代亚胺反应,得到 1,2-二芳基乙基(和丙基)胺,在苄基(仅取决于硫构型)和亚胺碳上均具有高立体选择性控制。anti:syn 比值介于 > 96: < 4 和 < 2: > 98 之间,取决于氮处的电子密度。
