The very labile dinitrogen complex [Mo(CO)(N2)(Ph2PCH2-CH2PPh2)2] has been described in detail. Its immediate precursor, [Mo(CO)(Ph2PCH2CH2PPh2)2], is obtained by the reaction of [Mo(N2)2-(Ph2PCH2CH2PPh2)2] with, for example, benzyl propionate under carefully controlled conditions (283, 322). This precursor is square pyramidal in the solid state, with carbon monoxide at the apex and an essentially vacant coordination position trans to it. The CO bond length is 1.192(12) A, and v(CO) = 1690 cm 1, and the nearest ap-... 

It is assumed that the preferred conformation of the substructure C=C—O—C of the configured ester enolate in the preferred transition state of the alkylation is that depicted in the center of the left-hand column of Figure 13.42. In the projection shown, the alkylating reagent reacts with the enolate from the front side for the reasons just stated. The reaction occurs with a diastereoselectivity of 97 3. Chromatography allows for the complete separation of the main diastereoisomer from the minor diastereoisomer. Reduction of the main diastereoisomer (for the mechanism, see Section 17.4.3) affords the alcohol B, a derivative of. S -a-benzyl propionic acid, with 100% ee. Hydrolysis of the benzylated esters without iso-... 

Fig. 13.42. Helmchen synthesis of enantiomerically pure a-alkylated carboxylic acids. The deprotonation of the propionic acid ester results in the "f "-enolate in the solvent THF and in the "Z"-enoLate in the solvent mixture THF/HHPA. In these projections, both enolates react preferentially from the front. The "f" -enolate results in a 97 3 mixture of 5- and fi-configured a-benzyl-propionic acid esters (X marks the chiral alkoxide group), while the "Z"-enolate results in a 5 95 mixture. Chromatographic separation and reduction of the C(=0)—Xc groups afford alcohol B with 100% ee from the " "-enolate and alcohol ent-B with 100% ee from the "Z"-enolate.

It was first observed that reactions of imines with ketene silyl acetals proceeded smoothly in the presence of 5 mol % Yb(OTf)3 (a representative lanthanide triflate) to afford the corresponding /3-amino ester derivative in a moderate yield. The yield was improved when Sc(OTf)3, rather than Yb(OTf)3, was used as catalyst (Eq. 3) [10]. Not only silyl enolates derived from esters, but also one derived from a thioester worked well to give the desired /3-amino esters and thioester in high yield. In the reactions of the silyl enolate derived from benzyl propionate, anti adducts were obtained with good selectivity. In addition, the catalyst could be recovered when the reaction was complete, and could be re-used.
