L-cysteine ethyl ester comprising an efficient - albeit unusual -Pd-catalyzed C-S coupling as the key step. Isoalliin is in demand in the field of Allium chemistry and serves as a standard for different determination methods in breeding research on Alliaceae, like onions, leek, or garlic.
天然硫化合物异蒜氨酸 (+)-(R)-3-[(E)-prop-1-enylsulfinyl]-2-aminopropanoic acid 由 L-半胱氨酸盐酸盐分五步合成为非对映异构体混合物乙酯包含一个有效的 - 尽管不寻常的 - Pd 催化的 CS 偶联作为关键步骤。异蒜素在葱属化学领域有需求,可作为葱、韭菜或大蒜等葱科育种研究中不同测定方法的标准。
