Abstract
Cyrene, a green bioderived solvent from waste cellulose, was applied to the synthesis of novel α-acyloxyamide derivatives through a Passerini-3CR with carboxylic acids and isocyanides with good yields and diastereoselectivities under mild conditions. Cyrene showed exceptionally high reactivity and the degree of diastereoselection was dependent mostly on the isocyanide. DFT calculations as well as the experimental findings indicated that both kinetic and thermodynamic effects might explain the results.

Abstract
A two-step enantioselective gram scale synthesis of the Persea derived γ-lactones (+)-majoranolide and (+)-majoranolide B has been achieved. The sequence uses the amine promoted crossed condensation of the biorenewable synthon Cyrene with aliphatic aldehydes followed by a Baeyer-Villiger oxidation. Comparison of optical rotation data with the natural products established the absolute configuration of the natural product series, and this work represents the first synthesis of these alkylidene natural products.

Abstract
Levoglucosenone (LGO) and structurally similar exo-cyclic enones derived from cyrene (dihydrolevoglucosenone) react with tropothione following the higher-order [8 + 2]-cycloaddition pathway. Reactions were performed at room temperature in CH2Cl2 solutions in absence of any activating reagent. Whereas reaction of tropothione with LGO occurred with complete stereoselectivity, leading to a single, sterically favored exo cycloadduct, identified as polycylic thiophene derivative, reactions performed with exo-cyclic enones yielded in some instances mixtures of two isomeric exo and endo cycloadducts, derived from spiro-tetrahydrothiophene as major and minor components, respectively, of the studied reaction mixtures. Exo and endo [8 + 2] cycloadducts differ in absolute configuration at the newly created chiral centers. Structures of exo and endo cycloadducts were confirmed by single crystal X-ray diffraction analysis.

Abstract
In the panorama of sustainable chemistry, the use of green solvents is increasingly emerging for the optimization of more eco-friendly processes which look to a future of biocompatibility and recycling. The green solvent Cyrene, obtained from biomass via a two-step synthesis, is increasingly being introduced as the solvent of choice for the development of green synthetic transformations and for the production of biomaterials, thanks to its interesting biocompatibility, non-toxic and non-mutagenic properties. Our review offers an overview of the most important organic reactions that have been investigated to date in Cyrene as a medium, in particular focusing on those that could potentially lead to the formation of relevant chemical bonds in bioactive molecules. On the other hand, a description of the employment of Cyrene in the production of biomaterials has also been taken into consideration, providing a point-by-point overview of the use of Cyrene to date in the aforementioned fields.

Abstract
![]()
The 1,5-HAT–1,2-(ester)alkyl
radical migration (Surzur–Tanner
rearrangement) radical/polar sequence triggered by alkoxyl radicals
has been studied on a series of C-glycosyl substrates
with 3-C-(α,β-d,l-glycopyranosyl)1-propanol
and C-(α-d,l-glycopyranosyl)methanol
structures prepared from chiral pool d- and l-sugar.
The use of acetoxy and diphenoxyphosphatoxy as leaving groups provides
an efficient construction of 10-deoxy-1,6-dioxaspiro[4.5]decane and
4-deoxy-6,8-dioxabicyclo[3.2.1]octane frameworks. The alkoxyl radicals
were generated by the reaction of the corresponding N-alkoxyphthalimides with group 14 hydrides [n-Bu3SnH(D) and (TMS)3SiH], and in comparative terms,
the reaction was also initiated by visible light photocatalysis using
the Hantzsch ester/fac-Ir(ppy)3 procedure.
Special attention was devoted to the influence of the relative stereochemistry
of the centers involved in the radical sequence on the reaction outcome.
The addition of BF3•Et2O as a catalyst
to the radical sequence resulted in a significant increase in the
yields of the desired bicyclic ketals.

Abstract
Efficient conditions have been developed for the diastereoselective aziridination of the biomass pyrolysis product (−)-levoglucosenone, via the reaction of primary aliphatic amines with 3-iodolevoglucosenone. In contrast to the reactions of aliphatic amines, the use of 4-methoxyaniline resulted in an aza-Michael-initiated dimerisation reaction, and 1,3-diphenylurea gave a 2-imidazolidinone. The aziridine products were transformed using the aza-Wharton reaction, affording novel sulfonamide and amine-substituted 6,8-dioxabicyclo[3.2.1]oct-3-enes with potential as sp3-rich chiral scaffolds.
