2-alkenyl-1,3-thiazolines 1 gives compounds 3 and 8 upon treatment with trichloroacetyl chloride and trifluoroacetic anhydride, respectively. This reaction is completely diastereoselective, in particular giving only a single double-bond isomer. The scope of the reaction has been evaluated synthetically, while a computational study has elucidated the mechanism of the reaction and the origin of stereocontrol
分别用三氯乙酰氯和三氟乙酸酐处理后,2-烯基-1,3-噻唑啉 1 的酰化二聚反应得到化合物 3 和 8。该反应是完全非对映选择性的,特别是只产生一个双键异构体。对反应的范围进行了综合评估,而计算研究阐明了反应的机制和立体控制的起源。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
