Cyrene是生物基双极性分子，生命周期终止处理后，安全降解成为CO2和H2O。可作为非质子类溶剂取代存在环境问题的普通溶剂。REACH将许多溶剂归为SVHC高度关注物质，其中包括N-甲基吡咯烷酮(NMP)和N,N-二甲基甲酰胺(DMF)，Cyrene™正是这些溶剂的替代品。

Dihydrolevoglucosenone (Cyrene) as a bio-based alternative for dipolar aprotic solvents
Sherwood, J., et al.

Beilstein journal of organic chemistry, 12, 2005-2011 (2016-11-11)
Pd-catalysed C-C bond formation is an essential tool within the pharmaceutical and agrochemical industries. Many of these reactions rely heavily on polar aprotic solvents; however, despite their utility, these solvents are incompatible with the drive towards more sustainable chemical synthesis.
Kirsty L Wilson et al.
Organic & biomolecular chemistry, 16(16), 2851-2854 (2018-04-10)
Amide bonds are one of the underpinning linkages in all living systems and are fundamental within drug discovery. Current methods towards their synthesis frequently rely on the use of dipolar aprotic solvents; however, due to increasingly stringent regulations and growing
Structure-reactivity correlations of the abnormal Beckmann reaction of dihydrolevoglucosenone oxime.
Amani Alhifthi et al.
Organic & biomolecular chemistry, 15(47), 10105-10115 (2017-11-25)
A structural, spectroscopic and computational study of a series of oximes was undertaken to investigate how geometric and structural changes relevant to the reaction coordinate for the Beckmann reaction (normal Beckmann) and Beckmann fragmentation (abnormal Beckmann) manifest in the ground

Chemical communications (Cambridge, England), 50(68), 9650-9652 (2014-07-10)
Dihydrolevoglucosenone (Cyrene) is a bio-based molecule, derived in two simple steps from cellulose, which demonstrates significant promise as a dipolar aprotic solvent. The dipolarity of dihydrolevoglucosenone is similar to NMP, DMF and sulpholane. Dihydrolevoglucosenone demonstrates similar performance to NMP in
