DOI: 10.1039/c9py01859j
Abstract: Herein, sequence-controlled polymerization and sequential Ugi-4CR/thiol–yne click reactions inspired a novel synthetic strategy for preparing a well-defined multigraft polymer in which the sequence-controlled amino-functionalized backbones were converted to mono- or di-modular alkynyl-functionalized main chains via… read more here.

DOI: 10.1055/a-1545-2860
Abstract: An efficient three-step synthesis towards 3-amino-1,4-benzodiazepin-2-one derivatives is presented. The versatile Ugi-4-component reaction (Ugi-4CR) and Boc deprotection is followed by a ligand-free Ullmann condensation. This protocol allows the rapid construction of a diverse array of… read more here.
