Jp. Mazaleyrat et M. Wakselman, SYNTHESIS OF NEW DIOXACYCLOPHANES DERIVED FROM 1,1'-BINAPHTHYL-2,2'-DIOL, Synthetic communications, 25(23), 1995, pp. 3845-3854
The Williamson reaction between (R,S)-[1,1'-binaphthyl]-2,2'-diol 1 an
d (R,S)-2,2'-bis (bromomethyl)-1,1' binaphthyl 2 in acetone, gave the
diastereoisomeric dioxacyclophanes (R,S*)-3a and (R*,R*)-3b in high y
ield.
