Conformational dependence of circular dichroism of 1,1′-spirobi[benz[e]indan]
Abstract
Three diastereomers of 3,3′-di-t-butyl-1,1′-spirobi[benz[e]indan], (lS,3R,3′R)-(1a), (1S,3S,3′S)-(1b), and (1S,3R,3′S)-(1c), have been prepared; c.d. spectral evidence is presented for their different conformations.
