A series oi 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 compoun
ds derived from diphenylmethoxymethyl pyrrolidine 2c, the C-2-symmetri
c pyrrolidines 2d-e and camphorsultam 2f. (C) 1998 Elsevier Science Lt
