TL;DR: In this article, the reduction of carbonyl compounds to alcohols with ammonia borane (AB), a nontoxic, environmentally benign, and easily handled reagent, in neat water was achieved in quantitative conversions and high isolated yields.
75 citations
TL;DR: An efficient and Brønsted acid free one-pot protocol to directly generate structurally sophisticated α-formylpyrrole derivatives in moderate to good yields has been demonstrated, involving an iron-mediated domino oxidation/formylation reaction of readily available 2,3-dihydro-1H-pyrroles in dimethyl sulfoxide and air atmosphere.
Abstract: An efficient and Bronsted acid free one-pot protocol to directly generate structurally sophisticated α-formylpyrrole derivatives in moderate to good yields has been demonstrated, involving an iron-mediated domino oxidation/formylation reaction of readily available 2,3-dihydro-1H-pyrroles in dimethyl sulfoxide and air atmosphere, in which dimethyl sulfoxide acts as the formyl donor. A possible mechanism is presented.

TL;DR: In this paper, a novel glycal-based O-glycosylation reaction, in which the substrates are not only peracetyl glycals but also perbenzyl glucals to afford the corresponding 2,3-unsaturated-O-glucosides via Ferrier rearrangement, was developed.

TL;DR: The first umpolung strategy for the cycloacylation of fullerene using a N-heterocyclic carbene organocatalyst is reported, and this new reaction displays a wide substrate scope and excellent functional-group tolerance.
36 citations
TL;DR: In this paper, a Ferrier rearrangement reaction and BF3·OEt2-induced peroxidation was employed to construct key intermediates 2,3-unsaturated glycosides and α,β-unaturated lactones from peracetyl rhamnal.

TL;DR: This review concludes that Etherification without Cyclization and N-Alkylation should be considered as separate science, and the proposed treatment of Etherification with Cyclization as a separate science should be reconsidered.

TL;DR: This tutorial review summarises recent progress in the development of novel and practical iron-catalysed reactions with a particular focus on those which provide access to new carbon-heteroatom and heteroatom-heteroa linkages.
Abstract: Given its ready availability, low price and environmentally friendly character, iron is an attractive and often advantageous alternative to other transition metals in the field of catalysis. This tutorial review summarises recent progress in the development of novel and practical iron-catalysed reactions with a particular focus on those which provide access to new carbon–heteroatom and heteroatom–heteroatom linkages. It shall be of interest for both the academic as well as the industrial community.

TL;DR: In this paper, the main developments on the employment of DMSO as sources of Me, SMe, SO2Me, as an oxidant etc. have been summarized and discussed.
Abstract: Dimethyl sulfoxide (DMSO) is one of the most commonly applied organic solvents in chemical transformations and is utilized widely in industrial processes as well. During the past decades, numerous procedures using DMSO as a reaction reagent have been developed and published. In this review, the main developments on the employment of DMSO as sources of Me, SMe, SO2Me, as an oxidant etc. have been summarized and discussed.
