Uemura, Takahito published the artcileA Concise Enantiodivergent Synthesis of Equol, SDS of cas: 16909-09-4, the publication is Synlett (2021), 32(7), 693-696, database is CAplus.
Equol, a nonsteroidal estrogen produced from the metabolism of the isoflavonoid phytoestrogen daidzein, has been synthesized as both enantioenriched forms based on MacMillan’s ¦Á-arylation of carbonyl compound mediated by amino acid derived indazolidinones and copper precatalysts. The natural form of (S)-equol and its enantiomer (R)-equol have been synthesized in 8 steps from 2,4-dimethoxybenzaldehyde with good enantiomeric purity (90% ee and 90% ee, resp.).
