Synthesis of C-glycosides via radical cyclization reactions with a vinylsilyl tether. Control of the reaction course by a change in the conformation of the pyranose ring due to steric repulsion between adjacent bulky protecting groups
TL;DR: In this paper, a stereoselective method for introducing a C 2 unit at the 1α and 1β-postions of d -glucose and d -mannose, respectively, via a radical cyclization reaction with vinylsilyl group as a temporary connecting tether, was developed.

Total synthesis of sandramycin and its analogues via a multicomponent assemblage.
TL;DR: The total synthesis of sandramycin has been accomplished by using a Staudinger/aza-Wittig/diastereoselective Ugi three-component reaction sequence as a key step to obtain a linear pentadepsipeptide.

A novel aldol-type C-glycosidation reaction promoted by samarium diiodide. Regioselective generation of a ulose-1-enolate from phenyl 3,4,6-tri-O-benzyl-1-thio-β-d-arabino-hexopyranosid-2-ulose
TL;DR: In this article, a novel aldol-type C-glycosidation reaction promoted by samarium diiodide (SmI 2 ) was developed, which was readily trapped with ketones or aldehydes to afford various C -glycosides in high yields.

A Synthesis Strategy for the Production of a Macrolactone of Gulmirecin A via a Ni(0)-Mediated Reductive Cyclization Reaction.
TL;DR: A synthesis strategy for the production of a key synthetic intermediate of gulmirecin A using an N-heterocyclic carbene ligand and silane reductant and the α-selective glycosylation reaction of the macrolactone was performed to demonstrate the synthesis of Gulmirecin and disciformycin precursors.

Total Synthesis of Acaulide and Acaulone A.
TL;DR: It is reported the first total synthesis of acaulide, acaulone A, and 10-keto-acaudiol A, which revealed the specific conformation of the 14-membered macrodiolide for late stage functionalization.
