European Journal of Organic Chemistry, EarlyView.Effective synthesis of 3‐substituted isoindolinones is possible through novel cascade reactions of alkyl arylacetates with 2‐cyanobenzaldehydes under mild, basic conditions. Herein we report the use of alkyl arylacetates as pro‐nucleophiles in cascade reactions with 2‐cyanobenzaldehydes leading to the formation of novel 3‐substituted isoindolinones, a ...

Traceable Traceless Delivery Tags
Helvetica Chimica Acta, EarlyView.ABSTRACT This study elaborates on traceless tags for the thiol‐mediated uptake (TMU) of amine‐containing substrates of interest (SOIs). Traceless tags typically contain linkers that can be enzymatically cleaved to trigger the release of SOIs in their native form.
