Description

(2S,3S)-4-(Anthracen-9-Yl)-3-(tert-Butyl)-2-Isopropyl-2,3-Dihydrobenzo[D][1,3]Oxaphosphole is a high-value, chiral organophosphorus compound featuring a unique oxaphosphole core fused with an anthracene moiety. This compound matters as a sophisticated ligand precursor or chiral auxiliary in asymmetric catalysis and pharmaceutical research, where its rigid, bulky structure can impart high stereoselectivity. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel synthetic methodologies and active ingredients.

Application

• As a chiral ligand or catalyst precursor in asymmetric synthesis, including hydrogenation and cross-coupling reactions.
• As a key synthetic intermediate in the research and development of novel pharmaceutical active ingredients.
• As a building block for advanced organic materials, such as organic light-emitting diodes (OLEDs) or liquid crystals, leveraging the anthracene chromophore.
• In academic and industrial R&D for studying structure-activity relationships (SAR) and new organocatalytic cycles.
• For the development of specialty agrochemicals requiring enantiomerically pure compounds.
• As a reference standard for analytical method development and quality control in chiral compound manufacturing.
