Highly effective and enantioselective phospho-Aldol reaction of diphenyl phosphite with N-alkylated isatins catalyzed by quinine (vol 52, pg 1157, 2011)

In our recent published Letter entitled 'Highly effective and enantioselective Phospho-Aldol reaction of diphenyl phosphite with N-alkylated isatins catalyzed by quinine', there was an inaccurate structural determination of the final product. We report here the correction of the structure via X-ray diffraction of the single crystal. The product should be alpha-oxindole-phosphonate, which was derived from the subsequent phospha-Brook rearrangement of the normal phospho-Aldol product. (C) 2011 Elsevier Ltd. All rights reserved.
