Optical resolution via catalytic generation of chiral auxiliary [PDF]

open access: yes, 2020
A new catalytic method for separating enantiomers of racemic compounds is proposed. Catalytic asymmetric addition of chiral trans-2-substituted cyclohexanols to imines provided diastereomeric mixtures of aminals, and the subsequent separation of the ...

Production of Biofuel via Hydrogenation of Lignin from Biomass [PDF]

open access: yes, 2017
Historically, humans have been harnessing biomass as a source of energy since the time they knew to make a fire from woods. Even today, some countries still depend on woods as a main source of energy. Biologically, biomass contains carbon-, hydrogen- and

A Kinetic Contribution to the Knowledge of Carbon-rings [PDF]

open access: yes, 1957
A mechanism involving a cyclic intermediate has been suggested by Welsh and Fodor independently. To obtain a deeper insight acyl shifts with (1) 2-acylamidocyclopentanol-cis (2) 2-benzamidocyclohexanol-cis and (3) trans have been -investigated ...
