and fragmentlibraries is an active area of research. The development of novel strategies to synthesise compounds with 3D character in order to expand the diversity of a fragmentlibrary was explored. A range of substituted bicyclo[2,2,1]spirooxindoles were synthesised using a Diels–Alder [4+2] cycloaddition reaction. Both diastereoisomers were isolated from the reactions and these 3D fragment scaffolds

Three distinct aminocatalytic cascadereactions leading to enantiomerically pure spirocyclic benzofuranones have been devised, highlighting the ability of organocascade to generate high degrees of stereochemical and architectural complexity in a single chemical transformation.
