Several complexes and silica-based nanohybrids of rare-earth ions (Eu3+, Gd3+) have been synthesized from dimethyl 4-azidopyridine-2,6-dicarboxylate (4) following the Click chemistry approach. A complete spectroscopic study indicates that such compou

The asymmetric synthesis of trifluoromethyl-piperidine-based γ-aminoacids and of indolizidines bearing a trifluoromethyl group is reported. These rarely described compounds are prepared in a highly enantio-enriched form employing as key step an intr

Copper(I)-catalysed azide-alkyne cycloaddition (CuAAC) has been successfully conducted under reductant-free conditions. The catalytic system consisted of a combination of a copper(I)-N-heterocyclic carbene complex and aromatic N-donors. The catalyst

The first asymmetric synthesis of (trifluoromethyl)pipecolic acids is reported. The synthetic strategy involves as key step an intramolecular Mannich reaction of a homochiral α-Tfm-β-amino ketal, prepared with a high stereoselectively in four steps

The highly diastereoselective synthesis of five trifluoro-substituted analogues of mono-, di-, and trisubstituted piperidine alkaloids was accomplished in two to four steps from 2-trifluoromethyl keto-protected 4-piperidones, prepared by an intramole

A new and highly stereoselective access to 4,10b-trans or 4,10b-cis hexahydropyrido[2,1-a]isoindole derivatives is reported, both requiring an intramolecular Mannich-type reaction as key step. The cis diastereoisomer is obtained in three steps from a

A highly diastereoselective 1,4-addition involving Davies' lithium amide is employed as the key reaction to prepare, in five steps from ethyl acetoacetate, an enantiomerically pure keto protected β,β ′ -ketoaminoester. This latter was reacted wit

An intramolecular Mannich reaction, involving various achiral aldehydes together with an α-chiral amine is employed as the key step for a stereocontrolled synthesis of highly substituted piperidine systems. Accordingly, 12 new piperidines bearing fo

An improved enantioselective synthesis (five steps, 37–44% yield versus seven to 10 steps, 13.5 and 12% yield, respectively) of both enantiomers of keto-protected 4-amino-2-pentanone has been realized, the key step being the microbiological reducti
