• Selective <i>tert</i>-Butyl Ester Deprotection in the Presence of Acid Labile Protecting Groups with Use of ZnBr₂

  hydrolysis of tert-butyl esters in the presence of other acid-labile groups has been explored by employing α-amino esters and ZnBr2 in DCM. Although N-Boc and N-trityl groups were found to be labile, PhF protected amines were compatible with these Lewis acid deprotection conditions such that a variety of N-(PhF)amino acids were prepared in good yields from their corresponding tert-butyl esters.

  通过在DCM中使用α-氨基酯和ZnBr 2，探索了在其他酸不稳定基团存在下叔丁基酯的化学选择性水解。尽管发现N -Boc和N-三苯甲基不稳定，但PhF保护的胺与这些路易斯酸脱保护条件兼容，因此可以从其相应的叔丁基酯中以高收率制备各种N-（PhF）氨基酸。

• 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

  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.
• Enantiospecific Synthesis of <i>N</i>-(9-Phenylfluoren-9-yl)-α-amino Ketones
  作者：M. Rita Paleo、M. Isabel Calaza、F. Javier Sardina

  DOI：10.1021/jo9707646

  日期：1997.10.1

  Enantiomerically pure N-(9-phenylfluoren-9-yl)-alpha-amino ketones were prepared in excellent yields by acylation of organolithium reagents with N-(9-phenylfluoren-9-yl)-alpha-amino acid-derived oxazolidinones. The method is not applicable for the acylation of Grignard reagents as they attack the methylenic carbon of the oxazolidinone to give the corresponding N-alkylated amino acids 13 in excellent yields. The resulting N-(9-phenylfluoren-9-yl)-alpha-amino ketones 8 could be stereoselectively reduced to the corresponding syn- or anti-beta-amino alcohols depending upon the nature of the reducing agent.
