New acylnitroso compounds for the asymmetric oxyamination of dienes
摘要:
A series of new enantiomerically pure acylnitroso compounds have been prepared and tested as dienophiles for the asymmetric oxyamination of dienes. Very high selectivities were obtained with acylnitroso compounds derived from diphenylmethoxymethyl pyrrolidine 2c, the C-2-symmetric pyrrolidines 2d-e and camphorsultam 2f.
