An alternative approach to chiral 2-[1' - (diphenylphosphanyl)ferrocenyl]-4,5-dihydrooxazoles

Abstrakt

The reaction of 1'-(diphenylphosphanoyl)ferrocenecarbonyl chloride, generated in situ by the reaction of 1'-(diphenylphosphanoyl)ferrocenecarboxylic acid and oxalyl chloride, with chiral aminoalcohols gave amidoalcohols, [Fe(h5-C5H4P(O)Ph2)(h5-C5H4C(O)NHCHRCH2OH)] 13, (R_= i-Pr, (S); R = i-Pr, (R); R = t-Bu, (S) and R = Ph, (R).
