“…The most explored chiral ligands types were phosphorus‐based ligands including phosphites,3 diphosphites,4 phosphoramidites,5 P,O‐6 and P,N‐ligands 7. Other classes of ligands explored, without a phosphorus atom, included chiral sulfonamides,8 diaminocarbenes,9 oxazolines,10 S,O‐,11 N,N‐12 and N,S‐13 ligands. On the other hand, binaphthol‐based ligands are some of the most widely studied in 1,4‐conjugate addition.…”
