不对称催化合成天然存在的具有生物活性的螺环化合物是现代化学方法学的一个挑战。本文报道了在易得的9-氨基-9-脱氧-表奎宁和N-叔丁氧羰基-D-苯基甘氨酸的催化下,二乙烯基酮与N-未保护的吲哚或N-苯基保护的吡唑啉酮发生[5+1]双Michael级联反应,合成螺环化合物。以高产率(高达98%)和立体选择性(高达>20:1 dr,99%ee)获得了所需的多立体异构螺[环己酮-羟吲哚和-吡唑啉酮]。
The asymmetric catalytic synthesis of naturally occurring and biologically active spiro compounds is a challenge for modern chemical methodology. Here we report the construction of spiro compounds through cascade [5+1] double Michael reactions between divinyl ketones and N-unprotectedoxindoles or N-phenyl-protected pyrazolones catalyzed by a combination of the easily available 9-amino-9-deoxy-epi-quinine with N-Boc-D-phenylglycine. The desired multistereogenic spiro[cyclohexanone-oxindoles and -pyrazolones] were obtained with high yields (up to 98 %) andstereoselectivities (up to >20:1 dr, 99 % ee).
