A tandem process, involving Rh(III)-catalyzed oxidative C–H olefination of enantiomerically enriched 4-aryl-benzo-1,3-sulfamidates and subsequent intramolecular aza-Michael cyclization has been developed. The reaction produces trans-benzosulfamidate-fused-1,3-disubstituted isoindolines as major products, in which the configurational integrity of the stereogenic center in the starting material is preserved
已经开发出一个串联过程,涉及对映体富集的4-芳基-苯并-1,3-氨基磺酸盐的Rh(III)催化的氧化CH烯化反应,以及随后的分子内氮杂-Michael环化反应。该反应产生作为主要产物的反式-苯甲酰胺基氨基磺酸盐稠合的1,3-二取代的异吲哚啉,其中保留了起始原料中立体异构中心的构型完整性。描述了苯并磺酰胺基稠合的1,3-二取代的异吲哚啉的进一步转化。
