Jjgs. Vanes et al., SYNTHESIS AND CHARACTERIZATION OF OPTICALLY-ACTIVE CYCLIC 6,6'-DINITRO-1,1'-BINAPHTHYL-2,2'-DIETHERS, Tetrahedron : asymmetry, 8(11), 1997, pp. 1825-1831
A series of racemic and enantiomerically pure 6,6'-dinitro-1,1'-binaph
thyl-2,2'-diethers 1 have been synthesized by the nitration of the cor
responding cyclic ethers and both the reactivity of nitration and the
(chir)optical properties proved to be very sensitive for the chain len
gth of the ether bridge. (C) 1997 Elsevier Science Ltd.
