Dependence of Copolymer Sequencing Based on Lactone Ring Size and ε-Substitution. [PDF]

open access: yesACS Macro Letters, 2016
The copolymerization of an ε-substituted ε-lactone, menthide (MI), and a range of nonsubstituted lactones (6-, 7-, 8-, and 9-membered rings) was investigated in order to determine the factors that affect the sequencing of the MI copolymers.

Keto-Enol Tautomerism in Passerini and Ugi Adducts

open access: yesMolecules, 2021
The use of arylglyoxal as starting material in Passerini and Ugi reactions affords β-ketoamides. This has allowed to study keto-enol tautomerism in these systems and assess the way in which the presence of acyloxy or aminoacyl groups bound to the C2 ...
