Modelling the response of Antarctic marine species to environmental changes. Methods, applications and limitations
Ecological modelling is nowadays widely used to highlight the environmental conditions that influence the species ecological niche and better understand their response to environmental changes. Methodological challenges are however present for Southern Ocean marine case studies and it is important ...
1-(4-Formyl-2,6-dimethoxyphenoxy)-4-chlorobut-2-yne
A reaction of biomass-derived aldehyde synringaldehyde and half an equivalent of 1,4-dichlorobut-2-yne was attempted in order to obtain a bis-aldehyde with an alkyne spacer. The reaction was carried out in a basic media to effect bis O-alkylation, as described in literature for the preparation of ...
