N-Butoxycarbonyl-5-oxo-l-proline ethyl ester
The mol-ecular structure of the title compound, C12H19NO5, may be visualized as made up of two nearly perpendicular planes [dihedral angle = 87.39 (12)°] and its crystal structure is a good example of C-H⋯O inter-actions assuming significance in optimizing supra-molecular aggregation in crystals in a mol-ecule which is severely imbalanced in terms of donors to acceptor atoms. The pyrrolidine ri...
متن کاملN-Acetyl-5-chloro-3-nitro-l-tyrosine ethyl ester
The title compound, C(13)H(15)ClN(2)O(6), was synthesized by hypochlorous acid-mediated chlorination of N-acetyl-3-nitro-l-tyrosine ethyl ester. The OH group forms an intra-molecular O-H⋯O hydrogen bond to the nitro group and the N-H group forms an inter-molecular N-H⋯O hydrogen bonds to an amide O atom, linking the mol-ecules into chains along [100]. The crystal studied was a non-merohedral tw...
متن کاملEthyl 4-acetyl-5-oxo-3-phenylhexanoate
The reaction of ethyl 3-bromo-3-phenyl-propano-ate with pentane-2,4-dione, in the presence of palladium(II) acetate and triphenyl-phosphine, in dimethyl-formamide, unexpectedly gave the title product, C(16)H(20)O(4). The mol-ecule contains one chiral C atom but the crystal is racemic. In the crystal, neighboring mol-ecules form a chain along [100] through three weak C-H⋯O inter-actions. Further...
متن کاملEthyl 5-oxo-2,3-diphenylcyclopentane-1-carboxylate
The title compound, C(20)H(20)O(3), was prepared by an acyl-oin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material. The C-O bond lengths for the carbonyl groups are 1.191 (2) and 1.198 (2) Å, while the C-O bond in the ester group is 1.335 (2) Å. The C-C bond lengths in the phenyl groups average 1.375 Å, while the C-C bonds in t...
متن کاملCrystal structure of 2-[N-(t-butoxycarbonyl)amino]-4-(thymin-1-yl)-butyric acid methyl ester.
psuedopeptide backbone composed of N-(2-aminoethyl) glycine units, and nucleobases are attached by methylene carbonyl linkers (Fig. 1). Since the binding of PNA to DNA inhibits transcription, the potential of PNA has been focused to target an antisense drug.1 Moreover, PNA-peptides hybridization and improvements of the PNA backbone unit were developed to form DNA-DNA-PNA triplexes with nonspeci...
