cis-4-(Sulfomethyl)piperidine-2-carboxylic acid was obtained in 22% overall yield from 4-(hydroxymethyl)-pyridine via the o-silyl N-oxide and trimethylsilylcyanide. The cis configuration of 5 was unambiguously assigned by 200 MHz 1H nmr and cosy experiments.
顺式-4-(磺基甲基)中的溶液在22%的总收率从4-(羟甲基) -吡啶得到哌啶-2-羧酸通过在ø -甲硅烷Ñ氧化物和三甲基甲硅烷。5的顺式构型由200 MHz 1 H nmr和舒适的实验明确指定。
