Tuning Pig Liver Esterase Enantioselectivity for the Synthesis of Unnatural Serine and Tyrosine Analogues [PDF]

open access: yes, 2009
The synthesis of disubstituted and homologated unnatural amino acids and the development of a mass spectrometry based assay for enantioselectivity are presented here. Disubstituted and homologated unnatural amino acids have proven to be effective for the

Synthesis of a-Amino-1-Adamantylacetic and a-Amino- 2-Adamantylacetic Acid [PDF]

open access: yes, 1976
a-Amino-2-adamantylacetic acid (VII) was obtained when 2-adamantylcyanoacetylhydrazide (IX) was subjected to Curtius rearrangement or 2-(2-adaman;tyl)-malonamic acid (XII) to Hofmann degradation.

Genetically Tunable Enzymatic C‒H Amidation for Lactam Synthesis [PDF]

open access: yes, 2019
A major challenge in carbon‒hydrogen (C‒H) bond functionalization is to have the catalyst control precisely where a reaction takes place. Here we report engineered cytochrome P450 enzymes that perform unprecedented enantioselective C‒H amidation ...

Rearrangement in folding potentials with density-dependent nucleon-nucleon interaction [PDF]

open access: yesarXiv, 2006
We discuss optical potentials for the nuclear elastic scattering from a variational viewpoint. Density-dependence in the effective $N$-$N$ interaction leads to density rearrangement terms, in addition to the conventional folding term. Effects of the rearrangement on the $N$-$A$ optical potential are illustrated in the nuclear-matter limit ...
