  On the Stereoselectivity of the Reaction of N-(9-Phenylfluoren-9-yl)aspartate Enolates with Electrophiles. Synthesis of Enantiomerically Pure 3-Hydroxy-, 3-Amino-, and 3-Hydroxy-3-methylaspartates

  摘要：

  We have developed efficient and stereoselective preparations of enantiomerically pure (3R)- and (3S)-N-Pf-3-hydroxy- and N-Pf-3-aminoaspartates by reaction of N-Pf-aspartate enolates with electrophilic hydroxylating or aminating reagents. The stereoselectivity of the hydroxylation and amination reactions was shown to be dependent on the structure of the enolate (which is strongly affected by the presence of strong metal complexing agents) and whether the electrophile is able to complex the enolate counterion in the transition state of the reaction. We have also developed a regioselective preparation of enantiomerically pure N-Pf-3-hydroxy-3-methylaspartates, albeit with only modest stereoselectivity.

  The oxidative dimerization of glycinates 1 with iodine takes place under kinetic control. The stereochemistry of the resulting 3-aminoaspartate 3 depends on the method used (base/solvent) to generate the corresponding enolate 2. Under suitable conditions, high yields and diastereomeric excesses in favor of the threo derivatives 3-I, which have C(2) symmetry, were obtained. In the presence of 8-phenylmenthol

  Homogeneous, Rh-catalyzed hydrogenation of heteromeric olefinic glycine dimers presents an efficient route to diastereomerically pure, orthogonally protected diaminosuccinic acid derivatives depending on the double bond geometry of the starting material. The products were obtained as racemates.
