The highly enantioselective addition of 1-fluoro-1,1-bis(phenylsulfonyl)methane (FBSM) to vinylogous imines generated in situ from 2-aryl-3-(1-arylsulfonylmethyl)indoles was achieved using chiral ammonium salts derived from cinchona alkaloids. One-pot conversion from 2-arylindoles with FBSM was also adaptable under the same reaction conditions. The key for this transformation is the effective use of
使用衍生自金鸡纳生物碱的手性铵盐可将1-氟-1,1-双(苯磺酰基)甲烷(FBSM)高度对映选择性地添加到由2-芳基-3-(1-芳基磺酰基甲基)吲哚原位生成的乙烯基亚胺中。 。在相同的反应条件下,2-芳基吲哚与FBSM的一锅转化也适用。该转化的关键是芳基磺酰基的有效利用。
