Taming tosyl azide: the development of a scalable continuous diazo transfer process [PDF]
, 2016 Heat and shock sensitive tosyl azide was generated and used on demand in a telescoped diazo transfer process. Small quantities of tosyl azide were accessed in a one pot batch procedure using shelf stable, readily available reagents. For large scale diazo

Biocatalytic Route to Chiral Precursors of β-Substituted-γ-Amino Acids [PDF]
, 2011 In this work, we utilized commercial lipases (from Thermomyces lanuginosa, Rhizopus delemar, and Mucor miehei) as biocatalysts for the efficient synthesis of precursors of β-substituted-γ-amino acids.

Enantioselective Route to Terminal 2,3-Epoxy Tosylates Enabled by Cooperative Organocatalytic Desymmetrization of 2-Substituted Glycerol Derivatives. [PDF]
ChemistryA desymmetrization strategy from bis tosylated 2‐substituted glycerols to challenging 2,2‐disubstituted 2,3‐epoxy tosylates has been developed using commercial L‐diphenyl prolinol/(R,R)‐TADDOL system or the enantiomeric catalytic couple. (R)‐ or (S)‐ epoxides are obtained in moderate to good yield and up to 76% ee. Useful elaborations to functionalized
