There is, no doubt, a decrease in the homoaromatic stabilization when conjugation is interrupted in two (bishomoaromatic) or more places (Paquette et al., 1977a Paquette, 1978). In spite of this, several bishomoaromatic cations have been well characterized. The simplest bishomoaromatic the 4-cyclopentyl cation [29] is, as yet, unknown (see Olah et al., 1972, and references cited therein). The cation [29] was not detected by NMR studies, nor was it invoked as an intermediate in the solvolysis of appropriately substituted cyclopentenes.

The cocrystal structure of 57 with ERa revealed that the more favorable interaction of the 5-OH with His524 compensates for the shift in the position of the D-ring required for binding with SERBA-1. Changing the ring size of the 3,4-cyclopentyl group to a cyclohexyl or cycloheptyl did not have much impact on either ER 3 affinity or selectivity. Attachment of a cyclopentanone (58) or cyclohexanone ring to the 3,4-position increased ERP selectivity to 100- and 40-fold, respectively, but also...
