Non-classicalC-saccharide linkage of dehydroalanine: synthesis ofC-glycoamino acids andC-glycopeptides

Abstract

Herein, a non-classical C-saccharides linkage is reported via C5 radical of pentoses or C6 radical of hexoses addition to Michael acceptors. The C(sp3)-S cleavage of glycosyl thianthrenium salts are developed...

Effects of multifunctional cerium-doped carbon dots on photosynthetic capacity and nutritional quality of lettuce

“…Therefore, the increase in calcium ion content is one of the important reasons that the Ce-CD treatment group promotes the growth and development process of production as well as biomass accumulation. 55,58 These results reveal that both 100 mg L −1 of Ce-CDs and 100 mg L −1 of CDs can promote the accumulation of different mineral elements, but the range of action is narrower and effect is weaker. 100 mg L −1 of Ce-CDs significantly enhance the accumulation of more mineral elements (Fig.…”

“…Mineral elements are indispensable components in establishing and maintaining plant growth and development. 55 They are not only the components of the cellular structure material of the plant body, but also involved in the regulation of plant absorption. The relative abundance of various mineral elements is important in photosynthesis in plants.…”

Reconfigurable Multifunctional van der Waals Ferroelectric Devices and Logic Circuits

“…However, it will be necessary to reduce the voltages used to program and operate the Re-FeFET in future work in order to compare fairly with conventional CMOS platforms. Identified pathways include reducing the thickness of the ferroelectric layer 46,71 and contact engineering. 67,68 Nevertheless, the high logic expressivity enabled by the simple Re-FeFET-based circuit under study will help to reduce complexity and increase logic circuit compactness through reconfigurability.…”

Nucleophilic functionalization of thianthrenium salts under basic conditions

“…A recent study by Shi and co-workers has successfully converted alcohols into thianthrenium salts, enabling the transformation of the hydroxy (OH) group into various functional groups via the photoassisted generation of alkyl radicals [39]. After that, a series of methods for the modification of alkylthianthrenium salts have been developed, including the transition-metal-catalyzed cross-coupling with terminal alkynes [40], sulfonylation with DABCO•(SO 2 ) 2 [41][42][43], or alkylation of active alkenes [44,45]. Recently, Ritter and co-workers reported that alkylthianthrenium salts can be employed to undergo reactions with N/O-nucleophiles under photocatalytic conditions [46].…”
