Bicyclic succinic anhydrides alkylated at the α-position have been prepared and submitted to alcoholysis in the presence of alkaloid bases. Anhydrides with a cyclopentane fused ring, open only from the less hindered side, generating monoesters of >8

The synthesis and liquid-crystalline properties are reported for novel bent-shaped dimers in which a naphthyl group has been incorporated into the mesogenic cores. In addition to the nematic and twist-bend nematic phase, a new liquid-crystalline phas

Herein we report a comprehensive study on novel carbonyl- and ethenyl-linked symmetric dimers that combine synthesis, mesomorphic properties and molecular modelling. The study has been focused on the impact of geometry imposed by the linkage group on

Liquid chromatography coupled with electrospray ionization mass spectrometry (ESI-MS) is routinely used in proteomics research. Mass spectrometry-based peptide analysis is performed de facto in positive-ion mode, except for the analysis of some post-

In addition to the varied biological activity of GABOB (4-amino-3-hydroxybutanoic acid), the structure of its protected derivatives makes them interesting chiral intermediates for the synthesis of more complex compounds. A stereoselective route to GA

The scope and limitation of the combined ruthenium-lipase induced dynamic kinetic resolution (DKR) through O-acetylation of racemic heteroaromatic secondary alcohols, i.e., 1-heteroaryl substituted ethanols, was investigated. After initial screening

An unexpected inversion of enantioselectivity, dependent on the degree of quinine loading, was observed during the desymmetrization of glutaric meso-anhydrides. Decrease in catalyst loading from 1.6 equiv to 0.1 equiv caused a clear inversion of ster

Four endo -isomers of (1 R ,2 S )-2-amino-4-methylenecyclopentanecarboxylic acid (+)- 1 (Icofungipen) have been prepared in enantiomerically pure form. Three endo -isomers were obtained by quinine-mediated kinetic resolution of a racemic anhydride, f
