Peptidomimetic tethered

Other reactions that have been applied in the Ugi postmodification strategy are the aza-Wittig reaction [80-84] and copper-catalyzed processes [85, 86], More recently, Domling and coworkers have developed a new approach for the synthesis of polycyclic compounds via Ugi MCR followed by a Pictet-Spengler reaction [87-89]. In 2011, apro-tocol for the rapid access to quinolin-2-(l//)-one scaffold was reported by a sequential 4-component Ugi-Knoevenagel condensation [90]. Hulme et al. have introduced a one-pot, two-step protocol for large-scale production of libraries of novel peptidomimetic-like fcM-pyrrolidinone tetrazoles via the Ugi-3CR-azide reaction of tethered keto ester methyl...
