The One‐Step Synthesis of Biologically Active Isochromans from Lignin‐Derived Aromatic Monomers in Tunable Deep Eutectic Solvents

Chemistry – A European Journal, EarlyView.
A straightforward one‐step protocol enables the synthesis of bio‐based and biologically active isochromans through the Oxa‐Pictet cyclization involving diverse aldehydes, including vanillin in combination with lignin‐derivable homovanillyl alcohol, a prominent aromatic platform chemical obtainable via diol‐assisted fractionation of lignocellulose ...

Synthesis and antimicrobial activity of novel sulfone-linked bis heterocycles

European Journal of Medicinal Chemistry, 2008
Novel sulfone-linked bis heterocycles pyrazolines in combination with thiadiazoles, oxadiazoles and triazoles were prepared from E-styrylsulfonylacetic acid methyl ester and tested for their antimicrobial activity. The compound 8 showed pronounced activity than the compounds 6 and 7.

Terahertz investigations on some bi-heterocyclic compounds

2016 21st International Conference on Microwave, Radar and Wireless Communications (MIKON), 2016
Terahertz spectral investigations on drug candidates with similar molecular structures to their chemical and physical parameters are described and newly-synthesized derivatives of some bi-heterocyclic compounds are examined. Using chemometric techniques we evaluate their spectral similarity in the THz range.
