Bengamide E is a bioactive natural product that was isolated from Jaspidae sponges by Crews and co-workers in 1989. It displays a wide range of biological activities, including antitumor, antibiotic, and anthelmintic properties. With the aim of inves

Enantiomerically pure β-aminoalcohols, produced through an organocatalytic Mannich reaction, were subjected to an Ugi multicomponent reaction under classical or Lewis acid-promoted conditions with diastereoselectivities ranging from moderate to good

The Ugi reaction of 2-substituted dihydrobenzoxazepines was found to proceed with unexpectedly good diastereoselectivitiy (diastereoisomeric ratios up to 9:1), despite the large distance between the pre-existing stereogenic centre and the newly gener

Starting from easily accessible chiral enantiopure 1,2-amino alcohols and salicylaldehydes, a concise route to cyclic imines has been developed. These chiral cyclic imines undergo a highly diastereoselective Ugi–Joullie reaction to give trans tetra

A novel synthetic strategy has been outlined to assemble enantiomerically pure Betti bases with unprecedented structures. This involves the Zr-mediated reduction of pyrrolidin-2-ones to cyclic imines and their subsequent reaction with phenolic deriva

A tandem Ugi/Mitsunobu protocol, starting from o-aminophenols, α-hydroxy acids, amines and aldehydes gives benzo[b][1,4]oxazin-3-ones of general formula 1 in two high-yielding steps, with the introduction of up to four diversity inputs. The mildness

With the goal of their exploitation for the synthesis of heterocycles, sulfides 10 and sulfones 11, derived from the initial ring-opening of 2-nitrothiophene (5) with pyrrolidine/AgNO3 in EtOH, were reacted with diazomethane. Interesting dichotomic b
