Abstract
In this note, supercritical fluid chromatography coupled to high-resolution mass spectrometry (SFC-HRMS) has been used to identify a chloro glycoside formed during the preparation of propargyl 1,2-orthoesters in dichloromethane. Additional studies revealed that 20-40% of this side-product was obtained depending on the source of anhydrous solvent, and that tetrabutylammonium iodide amplifies this side-reaction. Finally, a reliable procedure was developed in acetonitrile to prepare these glycosyl donors from perbenzoylated bromo glycosides in manno, gluco and galacto series in 63-74% yield.

Abstract
C-H functionalization has been emerging as a powerful method to establish carbon-carbon and carbon-heteroatom bonds. Many efforts have been devoted to transition-metal-catalyzed direct transformations of C-H bonds. Metal carbenes generated in situ from transition-metal compounds and diazo or its equivalents are usually applied as the transient reactive intermediates to furnish a catalytic cycle for new C-C and C-X bond formation. Using this strategy compounds from unactivated simple alkanes to complex molecules can be further functionalized or transformed to multi-functionalized compounds. In this area, transition-metal-catalyzed carbene insertion to C-H bonds has been paid continuous attention. Diverse catalyst design strategies, synthetic methods, and potential applications have been developed. This critical review will summarize the advance in transition-metal-catalyzed carbene insertion to C-H bonds dated up to July 2021, by the categories of C-H bonds from aliphatic C(sp3)-H, aryl (aromatic) C(sp2)-H, heteroaryl (heteroaromatic) C(sp2)-H bonds, alkenyl C(sp2)-H, and alkynyl C(sp)-H, as well as asymmetric carbene insertion to C-H bonds, and more coverage will be given to the recent work. Due to the rapid development of the C-H functionalization area, future directions in this topic are also discussed. This review will give the authors an overview of carbene insertion chemistry in C-H functionalization with focus on the catalytic systems and synthetic applications in C-C bond formation.

La Ferla B, D’Orazio G. Pyranoid Spirosugars as Enzyme Inhibitors. Curr Org Synth 2021; 18:3-22. [DOI: 10.2174/1570179417666200924152648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 08/25/2020] [Accepted: 08/31/2020] [Indexed: 11/22/2022]
Abstract
Background:
Pyranoid spirofused sugar derivatives represent a class of compounds with a significant
impact in the literature. From the structural point of view, the rigidity inferred by the spirofused entity has made
these compounds object of interest mainly as enzymatic inhibitors, in particular, carbohydrate processing enzymes.
Among them glycogen phosphorylase and sodium glucose co-transporter 2 are important target enzymes
for diverse pathological states. Most of the developed compounds present the spirofused entity at the C1 position
of the sugar moiety; nevertheless, spirofused entities can also be found at other sugar ring positions. The main
spirofused entities encountered are spiroacetals/thioacetals, spiro-hydantoin and derivatives, spiro-isoxazolines,
spiro-aminals, spiro-lactams, spiro-oxathiazole and spiro-oxazinanone, but also others are present.
Objectives:
The present review focuses on the most explored synthetic strategies for the preparation of this class
of compounds, classified according to the position and structure of the spirofused moiety on the pyranoid scaffold.
Moreover, the structures are correlated to their main biological activities or to their role as chiral auxiliaries.
Conclusion:
It is clear from the review that, among the different derivatives, the spirofused structures at position
C1 of the pyranoid scaffold are the most represented and possess the most relevant enzymatic inhibitor activities.
Nevertheless, great efforts have been devoted to the introduction of the spirofused entity also in the other positions,
mainly for the preparation of biologically active compounds but also for the synthesis of chiral auxiliaries
useful in asymmetric reactions; examples of such auxiliaries are the spirofused chiral 1,3-oxazolidin-2-ones and
1,3-oxazolidine-2-thiones.

Abstract
In this note, an hydrozirconation/bromination/Michaelis-Arbuzov sequence was developped to introduce a trimethylene phosphonate unit on ketopyranosides. Performed on polyfunctional substrates bearing orthogonal protecting groups, this new approach provided a straightforward entry towards a large diversity of glycophosphomimetics having a quaternary anomeric position.

Abstract
Transition-metal-catalyzed C-H functionalization and photoredox nickel dual catalysis have emerged as innovative and powerful avenues for the synthesis of C-branched glycosides. These two concepts have been recently established and provide efficient and mild methods for accessing a series of valuable complex C-branched glycosides of great interest. Herein, recent developments in the synthesis of C-branched aryl/alkenyl/alkyl glycosides through these two approaches are highlighted.
