Technical Notes:
1. The preparation of binaphthol monophosphoric acid derivatives.
2.Sigmatropic Rearrangements: Used in the organocatalytic aryl-aryl bond-forming process for the regio- and atroposelective synthesis of 2,2'-diamino-1,1'-binaphthalenes (BINAMs).In the presence of catalytic amounts of axially chiral phosphoric acids, achiral N,N'-binaphthyl hydrazines undergo a facile 3,3-
sigmatropic rearrangement to afford enantiomerically enriched BINAM derivatives in good to excellent yield.
