The proliferation of light-activated switches in recent years has enabled their use in a broad range of applications encompassing an array of research fields and disciplines. All current systems, however, have limitations (e.g., from complicated synthesis
Synthesis of Unprotected 2-Arylglycines by Transamination of Arylglyoxylic Acids with 2-(2-Chlorophenyl)glycine

The transamination of α-keto acids with 2-phenylglycine is an effective methodology for directly synthesizing unprotected α-amino acids. However, the synthesis of 2-arylglycines by transamination is problematic because the corresponding products, 2-arylglycines, transaminate the starting arylglyoxylic acids. Herein, we demonstrate the use of commercially available l-2-(2-chlorophenyl)glycine as the nitrogen source in the transamination of arylglyoxylic acids, producing the corresponding 2-arylglycines without interference from the undesired self-transamination process.
Zincation and Magnesiation of Functionalized Silylated Cyanohydrins Using TMP-Bases
Castelló-Micó, Alicia,Knochel, Paul
, p. 155 - 169 (2017/10/07)
Polyfunctional silylated cyanohydrins are readily magnesiated or zincated with TMPMgCl·LiCl or TMP 2 Zn·2MgCl 2 ·2LiCl leading to the corresponding metallated derivatives. These Mg- or Zn-derivatives react with various electrophiles such as benzylic bromides, allylic bromides, acid chlorides, aldehydes, NCCO 2 Et, or MeSO 2 SMe. Subsequently, TBAF-deprotection provides the corresponding keto or 1,2-diketo derivatives.
