Crystal structures and conformations of two Diels–Alder adduct derivatives: 1,8-bis(thiophen-2-yl)-14-oxatetracyclo[6.5.1.0(2,7).0(9,13)]tetradeca-2(7),3,5-trien-10-one and 1,8-diphenyl-14-oxatetracyclo[6.5.1.0(2,7).0(9,13)] tetradeca-2,4,6-trien-10-one

The title compounds, C(21)H(16)O(2)S(2) (I) and C(25)H(20)O(2) (II), are products of a tandem ‘pincer’ Diels–Alder reaction consisting of [2 + 2] cycloadditions between benzo[c]furan and cyclopentanone. Each comprises a fused tetracyclic ring system containing two five-membered rings (in envelop...
