- Synthesis of 6-tert-octyl and 6,8-ditert-butyl coumarins, two coumarins of biological interest
-
In this study, the synthesis of new coumarins with aliphatic chains is discussed. The incorporation of the 6-tert-octyl and 6,8-ditert-butyl chains into a coumarin structure from alkylphenols, allows obtaining hydrophobic coumarins with good yields. These coumarins can be potential modulators of TRPV1 receptors. Synthesis and spectroscopic data of these new coumarins are analyzed.

- The Rich Tautomeric Behavior of Campestarenes
-
Campestarenes are a new family of Schiff-base macrocycles that form selectively in a one-step synthesis. These macrocycles with five-fold symmetry show solvent-dependent tautomerization and dimerization or aggregation. In this paper, we have prepared new

- Campestarenes: Novel shape-persistent Schiff base macrocycles with 5-fold symmetry
-
A simple 1-step procedure yields a family of easily modifiable, stable, conjugated Schiff base macrocycles with 5-fold symmetry mediated by 3-center hydrogen bonding.

- The separation and synthesis of lipidic 1,2- and 1,3-diols from natural phenolic lipids for the complexation and recovery of boron
-
A study has been made of the semi-synthesis of 1,3-diols (anacardic alcohols) from natural phenolic lipid resources from Anacardium occidentale and Anacardium giganteum which have given C15 and C11 derivatives, respectively. An isomeric 1,3-diol (isoanacardic alcohol) has been obtained from cardanol separated from technical cashew nut-shell liquid. Homologous1,3-diols have been synthesised from a range of synthetic 2-alkyl-, 3-alkyl- and 4-alkylphenols and from 6-alkylsalicylic acids. The natural 1,2-diol, urushiol, from Rhus vernicifera has been purified. All these lipidic compounds have been studied for their complexation and the potential recovery of boron as boric acid.

- Nickel complex catalyzed reduction of imines
-
The 1:1 complexes formed in situ from nickel(II) acetate and the thiosemicarbazones of ortho-hydroxy aromatic aldehydes catalyze the hydrosilylation of imines. A variety of imines were reduced in good to excellent yields employing two equivalents of a silane such as triethylsilane and 5 mol% of the catalysts.
