New photochemically removable protecting groups have been developed based on classical nitrobenzyl compounds modified by the inclusion of a pentadienyl group. It serves to trap through an internal Diels-Alder reaction the nitroso group produced as part of the photochemical deprotection process, preventing its further photochemistry or chemical reactions with nucleophiles.
First catalyst-free CO2 trapping of: N -acyliminium ions under ambient conditions: Sustainable multicomponent synthesis of thia- and oxazolidinyl carbamates

The first trapping of N-acyliminium ions by in situ generated carbaminic acid (product of carbon dioxide (CO2) and amine) is reported. This catalyst-free reaction provides a convenient and feasible approach to prepare N-acyl thia- and oxazolidi

An on-line coupled HPLC system is described for the kinetic study of the enantiomers of 1-methyl-2-piperidinoethylesters of 2-, 3- and 4-alkoxyphenylcarbamic acid in rabbit blood serum. The method involves three steps: (i) off-line pre-concentration and cleanup step, (ii) analytical separation of the racemate on a reversed-phase stationary phase, and (iii) separation of the enantiomers on a teicoplanin aglycone chiral stationary phase (Chirobiotic Tag). The limit of the determination with standard solutions was approximately 5.0 μg/ml. In vitro degradation studies of enantiomers have demonstrated differences in the concentration of the enantiomers after the treatment. The rate constants of R(-)- and S(+)-forms of enantiomers (the same as the position of alkoxychain) were, not significantly different. The number of carbon atoms had an influence on the degradation kinetics.
