SnAP Reagents for the Synthesis of Piperazines and Morpholines
, 2016 Substituted piperazines and morpholines are valuable structural motifs in biologically active compounds, but are not easily prepared by contemporary cross-coupling approaches. In this report, we introduce SnAP reagents for the transformation of aldehydes

Heterocyclic Merging of Stereochemically Diverse Chiral Piperazines and Morpholines with Indazoles [PDF]
, 2023 We report a heterocyclic merging approach to construct novel indazolo-piperazines and indazolo-morpholines. Starting from chiral diamines and amino alcohols, novel regiochemically (1,3 and 1,4) and stereochemically diverse (relative and absolute) cohorts
