Abstract

The preparation of highly diastereo-and enantiomerically enriched planar chiral 1- phenylsulfonyl-substituted tricarbonyl (η5-pentadienyl) iron (1+) complexes 7 [syn, syn-(1 R, 5R)-7 and syn, syn-(1S, 5S)-7 (cisoid-or U-forms); de> 99% 5-syn-CH3/5-anti-CH3⪢ 100: 1, ee> 99%; 87% quant. from resolved 6] is described. Starting from the enantiopure diene (1 E, 3 E, S)-5 both enantiomers of the cationic complexes syn, syn-7 become readily ...
