Chiral C2-symmetric N-benzylazetidines have been conveniently prepared from optically pure anti-1,3-diols without loss of enantiomeric purity. N-Debenzylation led to the corresponding N-unsubstituted azetidines, which were then subjected to palladium-catalysed coupling reactions with aryl bromides to afford chiral N-arylazetidines. (R,R)-N-Benzyl-2,4-dimethylazetidine has been employed in the synthesis
手性 C2 对称 N-苄基氮杂环丁烷可以方便地从光学纯的抗 1,3-二醇制备,而不会损失对映体纯度。N-脱苄基化生成相应的 N-未取代氮杂环丁烷,然后将其与芳基溴化物进行钯催化偶联反应,得到手性 N-芳基氮杂环丁烷。(R,R)-N-Benzyl-2,4-二甲基氮杂环丁烷已用于合成新的环钯络合物,例如,可用作磷配体的手性识别剂。
