A new synthetic route to 2-alkyl-4-aryl-1(2H)-isoquinolones and 2-alkyl-4-aryl-1,2,3,4-tetrahydroisoquinolines

4-Aryl and heteroaryl-1(2H)-isoquinolones have been prepared by base promoted cyclization of phosphorylated o-aroyl and heteroaroyl benzamides. Subsequent reduction of the carbonyl and styryl functions of the annulated products has given rise to 4-aryl-1,2,3,4-tetrahydroisoquinolines.

Synthesis of bicyclic carbamates as precursors of Sedum alkaloid derivatives

Synthesis of a N-Boc-protected piperidin-2-yl phosphine oxide starting from piperidine in three steps, followed by olefination using a variety of α,β-unsaturated aldehydes resulted in tert-butyl 2-(2′- alkenylidene)piperidine-1-carboxylates in high yields

First synthesis and pharmacological evaluation of benzoindolizidine and benzoquinolizidine analogues of α- and β-peltatin

The benzoindolizidine and-quinolizidine analogues of α- and β-peltatin were designed and synthesized by two different synthetic routes involving as the key step the Bischler-Napieralski cyclization of suitably substituted N-acyl-2-arylmethylpyrrolidine and -piperidine derivatives. The in vitro biological activity of these analogues as well as some of their derivatives was subsequently evaluated. Copyright (C) 2000 Elsevier Science Ltd.

An efficient synthesis of 5-(or 6-)-arylbenzoindolizidine and - quinolizidine derivatives

A new methodology for the synthesis of (hetero)arylated benzomdolizidine and benzoquinolizidine derivatives through sequential reduction of pyrrolidine- and piperidine-based aromatic enamides, and ultimate cyclization, is reported.

Dramatically different photochemical behaviour of 1-aroyl-2-methylene piperidine and pyrrolidine derivatives. An expeditious synthesis of ruspolinone

Upon irradiation in neutral solvent, the diversely substituted 1-aroyl-2-methylenepiperidines 6a-f give rise to photocyclized products 4a-f while their pyrrolidine congeners 7a,c,d afford enaminoketones 18a,c,d products of photo-Fries rearrangement.
