TL;DR: In this article, 1,3-dimethyluracil was used to give pyrazolo[1,5-a]pyrimidine C-nucleosides, which were separated on a silica gel column.

TL;DR: In this article, the temperature variation of the matrix ENDOR linewidth of γ-irradiated sucrose is interpreted as being due to the modulation of the dipolar electron spin-proton interactions by lattice vibrations.

TL;DR: The use of pyranose glycals in the creation of skeletally-diverse derivatives has been investigated in the literature during the last eight years as mentioned in this paper, where the presence of an unsaturation in a pyrano-synthetic derivative provides a powerful handle for creating new compounds displaying a variety of molecular skeletons.
Abstract: The presence of an unsaturation in a pyranose derivative provides a powerful handle for the creation of new compounds displaying a variety of molecular skeletons. This contribution focuses on investigations related to the use of pyranose glycals in the creation of skeletally-diverse derivatives that have appeared in the literature during the last eight years.

TL;DR: In this article, three enzymatic treatments were compared for the depolymerization of cellulolytic enzyme lignin (CEL) from aspen; these systems used pyranose 2-oxidase and Lignin-degrading peroxidases.
Abstract: Three enzymatic treatments were compared for the depolymerization of cellulolytic enzyme lignin (CEL) from aspen; these systems used pyranose 2-oxidase and lignin-degrading peroxidases. The “P” system was mainly composed of pyranose 2-oxidase, lignin peroxidase (LiP), and manganese peroxidase (MnP). Catalase and vitamin C were added to the P system to decompose H2O2 to control the H2O2 concentration. The system to which catalase was added was called the “C” system. The system to which catalase and vitamin C were added together was called the “V” system. Ultraviolet-visible (UV-Vis) spectra of supernatants after aspen CEL treatment by the P, C, or V system was used to monitor the amount of water-soluble lignin fragments that were generated, which increased with system treatment time. A gel permeation chromatography (GPC) analysis showed that after 12 h of system treatment, the molecular weight (Mw) of CEL was efficiently lowered; the maximum Mw reduction of aspen CEL was 20% when compared to the blank and control runs. The residual enzymatic activity of the supernatant after the CEL treatment by the P, C, or V system indicated that MnP and LiP activity for lignin degradation was dependent upon the H2O2 concentration. Therefore, it is advised that MnP and LiP be applied separately for effective lignin degradation.
