1,4-Bis(4-tolylsulfonyl)-1,2,3,4-tetrahydropyridines undergo stereoselective SN1 reactions with soft carbon nucleophiles in the presence of Lewis acids. Subsequent dihydroxylation of the double bond followed by esterification enables the stereoselective preparation of substituted piperidines.
在路易斯酸存在下,1,4-双(4-甲苯磺酰基)-1,2,3,4-四氢吡啶与软碳亲核试剂进行立体选择性S N 1反应。随后双键的二羟基化,然后进行酯化,可以立体选择性地制备取代的哌啶。
