- Synthesis of arylglycine and mandelic acid derivatives through carboxylations of α-amido and α-acetoxy stannanes with carbon dioxide
-
Incorporation reactions of carbon dioxide (CO2) with N-Boc-α-amido and α-acetoxy stannanes were developed using CsF as a mild tin activator. Monoprotected α-amido stannanes could be used, and the corresponding arylglycine derivatives were obtained in moderate-to-high yields under 1 MPa (10 atm) of CO2 pressure. α-Acetoxy stannanes also underwent carboxylation to afford mandelic acid derivatives in excellent yields under ambient CO2 pressure. Both transformations enabled the synthesis of α-tertiary and α-quaternary carboxylic acid derivatives. In addition, the chirality of (S)-N-tert-butylsulfonyl-α- amido stannanes was transferred with up to 90% inversion of configuration at 100 °C.

- One-pot synthesis of α-amino acids from imines through CO2 incorporation: An alternative method for strecker synthesis
-
Itas a gas: A novel one-pot process for the synthesis of α-amino acids from imine equivalents using CO2 gas as a carbon source has been developed. This reaction was made possible by the reagent combination of TMSSnBu3 and CsF (see scheme). Three successive reactions (imine formation, stannylation, and carboxylation) proceeded in the same flask under these conditions to give products in up to 79 % yield. Boc=tert-butoxycarbonyl, TMS=trimethylsilyl.

- Chemo-enzymatic dynamic kinetic resolution of amino acid thioesters
-
The L-forms of racemic-N-protected-β,γa,aunsaturated a-amino acid thioesters were found to be substrates for the subtilisin-catalysed hydrolysis to the corresponding acids. The D-enantiomer was continuously racemised in the presence of an organic base. The combined reactions in a biphasic system allowed the deracemisation of the amino acid derivatives based on a dynamic kinetic resolution. Excellent yields and enantioselectivities were achieved.
