  Organocatalytic, Asymmetric Synthesis of 3-SulfenylatedN-Boc-Protected Oxindoles

  摘要：

  Sulfenylated oxindoles: The first asymmetric sulfenylation of N-Boc-protected oxindoles has been developed to provide products containing a tetrasubstituted stereogenic center in high to excellent yields (86-98 %) and, in most cases, excellent enantioselectivities (up to 96 % ee; see scheme).

  3′‐disubstituted oxindoles—3‐furanyl‐ and 3‐pyrrolyl‐3‐alkyl‐oxindoles—in high yields and good enantioselectivities. Notably, the studies presented here sufficiently confirm that this two‐step strategy of sequential conjugate addition/Paal–Knorr cyclization is not only an attractive method for the indirect enantioselective heteroarylation of 3‐alkyloxindoles, but also opens up new avenues toward asymmetric synthesis

  3-单取代的羟吲哚的不对称共轭加成范围为（E）描述了由市售的辛可宁催化的1,4-二芳基-2-丁烯-1,4-二酮。这种有机催化不对称反应提供了范围广的3,3'-二取代的羟吲哚，这些化合物包含1,4-二羰基部分以及附近的季铵和叔立体中心，收率高至优异（高达98％），并具有出色的非对映异构体和中高对映体比例（分别高达99：1和95：5）。随后，在不同的Paal–Knorr条件下，所得迈克尔加合物中1,4-二羰基部分的环化产生了两种新型的3,3'-二取代的羟吲哚——3-呋喃基和3-吡咯基-3-烷基-氧吲哚-高收率和良好的对映选择性。尤其，
