An unusual kinetic approach to the Pictet–Spengler reaction was investigated, in which l - or d -tryptophan methyl ester reacted with aldehydes of 1,2- O -cyclohexylidene-3-allyloxy-α- d -xylofuranose, yielding exclusively the cis or trans diastereomer of tetrahydro-β-carboline glycoside, respectively, with complete stereocontrol.
研究了 Pictet-Spengler 反应的一种不寻常的动力学方法,其中 l-或 d-色氨酸甲酯与 1,2-O-环己叉-3-烯丙氧基-α-d-木呋喃糖的醛反应,仅产生顺式或分别具有完全立体控制的四氢-β-咔啉糖苷的反式非对映异构体。
