| pubmed-article:21200889 | pubmed:abstractText | In the title compound, C(17)H(19)NO(7), the cyclo-pentane ring is in an envelope conformation in which the methyl-ene group forming the flap is cis to the cyclo-propane group. The relative configuration between the 4-nitro-benzo-yloxy substituent on the side chain and the cyclo-propane ring is trans and the methoxy-lmethyl group adopts the expected conformation in which the two O atoms are gauche to one another. | lld:pubmed |
