The title compound crystallizes in the space group Pna21, with a = 10.124(5), b = 14.335(3), c = 11.113(2) Å. There is no conjugation between the purine moiety and the cyclopentane ring, whereas there is some conjugation between the isoxazoline and the phenyl rings. The chiral centers C3a, C4, C6a, C6 are either S, S, R, R or R, R, S, S respectively, because of the glide planes. The molecules are linked by intermolecular hydrogen bonds and van der Waal's forces.

Abstract

The title compound crystallizes in the space group Pna21, with a = 10.124(5), b = 14.335(3), c = 11.113(2) Å. There is no conjugation between the purine moiety and the cyclopentane ring, whereas there is some conjugation between the isoxazoline and the phenyl rings. The chiral centers C3a, C4, C6a, C6 are either S, S, R, R or R, R, S, S respectively, because of the glide planes. The molecules are linked by intermolecular hydrogen bonds and van der Waal's forces.

The Organic Chemistry/Polymer Science category includes resources concerned with the related fields of organic chemistry and polymer science. The organic chemistry resources deal with compounds of carbon with the exception of certain simple ones, such as the carbon oxides, carbonates, cyanides and cyanates (see Inorganic & Nuclear Chemistry). This category includes research on synthetic and natural organic compounds that may include other elements, such as hydrogen and oxygen, but also nitrogen, halogens, sulphur and phosphorous. Resources concerned with hydrocarbons, organic compounds containing only the elements carbon and hydrogen, are also included in this category. Examples are the alkanes, alkenes, alkynes and aromatics, such as benzene and naphthalene. Polymer science includes all resources dealing with the study, production and technology of polymers, which are compounds composed of very large molecules made up of repeating molecular units (monomers). Polymers may be natural substances, such as polysaccharides or proteins, or synthetic materials, such as nylon or polyethylene.
