The reaction of sodium diselenide with optically active alkyl tosylates or chlorides is found to be a useful method for the synthesis of optically active dialkyl diselenides. Optically active monoterpene diselenides derived from menthane, carane, pinane, and bornane systems have been obtained. The influence of the terpene fragment of the obtained diselenides on the diastereomeric excess of the methoxyselenylation
发现二硒化钠与光学活性的甲苯磺酸烷基酯或氯化物的反应是合成光学活性二烷基二硒化物的有用方法。已经获得衍生自薄荷烷、卡拉烷、蒎烷和冰片烷系统的旋光单萜二硒化物。已经研究了所得二硒化物的萜烯片段对甲氧基硒化产物的非对映体过量的影响。对于 (-)-二异松香叶二硒化物观察到甲氧基硒化的最佳结果。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
