Mechanochemistry in Organic Synthesis: An Italian Journey through Innovations

open access: yesEuropean Journal of Organic Chemistry, Volume 27, Issue 30, August 12, 2024.
The contribution of Italy to the development of mechanochemistry dates back to 1988 with the first studies on metal alloys. With the progress of time, it has flourished not only in the field of organic chemistry, but also in other scientific fields due to the enormous interest of Italian researchers in the various advantages brought by this technique ...

Assessment of Mechanisms Involved in Antinociception Produced by the Alkaloid Caulerpine

open access: yesMolecules, 2014
In previous works we showed that oral administration of caulerpine, a bisindole alkaloid isolated from algae of the genus Caulerpa, produced antinociception when assessed in chemical and thermal models of nociception.

Molecular Networking‐Guided Discovery of Kyonggic Acids in Massilia spp.

open access: yesEuropean Journal of Organic Chemistry, Volume 27, Issue 17, May 3, 2024.
The metabolomes of six Massilia strains were analyzed using a molecular‐networking guided approach, revealing interconnections among metabolites. A closer inspection of the most promising strains led to the discovery of novel N‐acylated amino acids, termed kyonggic acids.

The Raputindoles: Novel Cyclopentyl Bisindole Alkaloids from Raputia simulans

open access: yesOrganic Letters, 2010
A novel class of bisindole alkaloids is established by the isolation and structural determination of raputindoles A-D (1-4) from the Amazonian plant Raputia simulans Kallunki (Rutaceae). Complete spectroscopic characterization was accomplished by means of NMR spectroscopy and APCI (+) HRMS.

Attempted Synthesis of Vinca Alkaloids Condensed with Three-Membered Rings

open access: yesMolecules, 2018
Our successful work for the synthesis of cyclopropanated vinblastine and its derivatives by the Simmons–Smith reaction was followed to build up further three-membered rings into the 14,15-position of the vindoline part of the dimer alkaloid ...
