K. Mislow, P. Bickart, Isr. J. Chem. 1976/1977, 15, 1. In considering what the term "cryptochiral" is meant to describe, one has to point out a serious deficiency, as any racemate might also be called cryptochiral. "Crypto-optically active" appears to be a more appropriate term.

2) = 0.141 for all data (153 parameters), conventional R(F) = 0.0524 for 587 reflections with I ≥ 2σ(I). GOF = 1.033. The absolute configuration was assigned on the basis of the known R configuration of 5; the Flack parameter for the reported configuration is 0(5) and for the inverted model 1(5). Crystallographic data (excluding structure factors) for the structure reported in this paper have been deposited with the Cambridge Crystallographic Data Centre as supplementary publication no.

aromaticity is not a precondition for the rotatory strengths of compounds of type 2, as the spiro-annelated cyclopropane subunits are perpendicular with respect to each other
-
Despite the fact that this suggested nomenclature may lead to an association with the σ-aromatic character of the cyclopropane ring (see D. Cremer, Tetrahedron 1988, 44, 7427-7454), aromaticity is not a precondition for the rotatory strengths of compounds of type 2, as the spiro-annelated cyclopropane subunits are perpendicular with respect to each other.
