Stereoselective Iodocyclization of 3-Acylamino-2-methylene Alkanoates: Synthesis of Analogues of N-Benzoyl-syn-phenylisoserine
摘要:
A convenient approach to racemic analogues of N-benzoyl-syn-phenylisoserine was realized via the stereoselective iodocyclization of amides obtained from Baylis-Hillman adducts.

The first organocatalysed enantioselective [1,3]-sigmatropic O- to N-rearrangement reactions are presented. The reactions take place under regio- and enantioselective control, and are catalysed by cinchona alkaloids. Two reactions have been developed the first one is the rearrangement of imidates to amides, while the other rearrangement occurs from carbamates to amines via a decarboxylation. Both transformations
