摘要：

The chloro-bridged complexes [Cp{black star}MCl2]2 (M = Rh,Ir; Cp{black star} = η5-C5Me5) and [Rh(CO)2Cl]2 react with C-allylglycine esters to give the N,η2-C,C-chelate complexes [Cp{black star}(Cl)M NH2CH(CO2Me)CH2CHCH2]+BF4- (1a,b) and OC(Cl)Rh-NH2CH(CO2R1)CH2C(R2)CH2 (2), respectively (R1 = Me, Et; R2 = H,Me). Regiospecific and stereoselective addition of HCl and P(OMe)3 to 2 yields via (MeO)3P(Cl)2RhC(Me)(R2)CH2CH(CO2R1)NH2 (4) the chloro-bridged compounds {(μ-Cl)(Cl)[(MeO)3P]RhC(O)C(CH3)(R2)CH2CH(CO2R1)NH2}2 (5). Reaction of 5a with P(OMe)3 in methanol gives the γ-lactam 4-cis-methyl-5-oxo-2-pyrrolidine carboxylic acid methylester (6), [Cp{black star}MCl2]2 and allylglycinate give the N,O-chelate complexes Cp{black star}(Cl)MNH2CH(CH2CHCH2)COO (M = Rh,Ir) (7). The structures of 1b and 5b have been determined by X-ray diffraction. © 1990.
