(2R)-N-Glyoxyloylbornane-10,2-sultam reacted with dopamine hydrochloride, forming the Pictet-Spengler condensation product, which was further converted into (S)-(+)-N)-methylcalycotomine of high enantiomeric purity. The same kind of reaction with tryptamine hydrochloride gave the condensation product with 100% d.e.
(2R)-N-糖苷酸基bornane-10,2-磺酰胺与多巴胺盐酸盐发生反应,形成了Pictet-Spengler缩合产物,该产物进一步转化为高对映体纯度的(S)-(+)-N-甲基calycotomine。同样的反应与色胺盐酸盐反应,生成了具有100%对映体过量的缩合产物。
