Synthesis of enantiomerically pure 2,2'-dihydroxy-1,1'-binaphthyl, 2,2'-diamino-1,1'-binaphthyl, and 2-amino-2'-hydroxy-1,1'-binaphthyl
Synthesis of enantiomerically pure 2,2'-dihydroxy-1,1'-binaphthyl, 2,2'-diamino-1,1'-binaphthyl, and 2-amino-2'-hydroxy-1,1'-binaphthyl. Comparison of processes operating as diastereoselective crystallization and as second order asymmetric transformation. Smrcina, Martin; Lorenc, Mirolsav; Hanus, Vladimir; Sedmera, Petr; Kocovsky, Pavel (Dep. Org. Chem., Charles Univ., Prague 128 40, Czech.). J. Org. Chem., 57(6), 1917-20 (English) 1992. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) The title compds. I (R = R1 = OH, NH2; R = OH, R1 = NH2) were prepd. in enantiomerically enriched forms by oxidative coupling of the corresponding naphthyl derivs. 137848-29-4 and 137848-28-3 are also in the experiment. using complexes of CuCl2 and chiral amines (sparteine or a-methylbenzylamine). Pure enantiomers were obtained via crystn. of enriched samples. A 2nd-order asym. transformation was obsd. for crystn. of I (R = R1 = OH) via a complex. .
