Lisa Moni,Luca Banfi,Andrea Basso,Andrea Bozzano,Martina Spallarossa,Ludger A. Wessjohann,Renata Riva +6 more
TL;DR: A series of Passerini reactions on a biocatalytically derived enantiopure azetidine-2-carboxyaldehyde is explored to obtain, in a diastereoselective manner, polyfunctionalised derivatives having the potential to be cyclized to chiral bridged bicyclic nitrogen heterocycles.
