Dihydrolevoglucosenone (Cyrene) is a bicyclic, chiral, seven-membered heterocyclic cycloalkanone which is a waste derived and fully biodegradable aprotic dipolar solvent. [4] [5] [6] It is an environmentally friendly alternative to dimethylformamide (DMF) …

Cyrene is a biobased dipolar, safe for end-of-life disposal, decomposing into CO 2 and H 2 O. It is an aprotic alternative to common solvents that are of environmental concern.

Structure of Cyrene and its most relevant “green” properties. Chemically, Cyrene is a bicyclic ketone that bears an intramolecular acetal functionality, synthetically accessible through two-step processes starting from biomass .

Dihydrolevoclucosenone (Cyrene is its market name) is a biomass-derived solvent that can be produced in only two steps from biomass, while being biodegradable, non-mutagenic and non-toxic. Its “green” profile combined with its physical properties makes Cyrene a plausible substitute for a number of widely used toxic organic solvents.

2022年4月1日 · Cyrene (dihydrolevoglucosenone) is a green dipolar aprotic solvent prepared by pyrolysis of cellulose-containing biomass. Cyrene possesses a beneficial occupational health and safety profile combined with good biodegradability without NO x or SO x production.

Regarding its chemical structure, Cyrene is an optically active ketone composed of two fused rings, which form a cyclic acetal (Scheme 1). The ring fusion results in a double anome-ric e ect, which stabilizes the existence of the cyclic acetal.5In. tions taking place in …

2021年1月1日 · Cyrene (dihydrolevoglucosenone) is a sustainable, easily biodegradable, and nontoxic solvent derived from cellulose-containing biomass. Being a dipolar, aprotic, and high boiling point solvent, Cyrene is often considered as a green alternative to DMF and NMP.

2024年10月31日 · Dihydrolevoglucosenone (Cyrene) is a high boiling point solvent derived from cellulose. As an alternative solvent, Cyrene has been used in organic reactions, metal-catalyzed reactions, and biocatalysis.
