Application
This chiral isothiourea homobenzotetramisole ((R)-HBTM) developed by the Birman lab is an organocatalyst that has been used for kinetic resolution, determination of absolute configuration, and nucleophile-catalysed, Michael–aldol-b-lactonization (NCMAL). This same product was previously listed as L511730, and the complementary (S)-HBTM organocatalyst (900542) is also available.
