Collis, Gavin E., Dylan Jayatilaka, and Dieter Wege. "Cyclopropa-Fused Quinones. The Generation and Trapping of Bicyclo[4.1.0]hepta-1(6),3-diene-2,5-dione and 1H-Cyclopropa[b]naphthalene-2,7-dione." Australian Journal of Chemistry 50, no. 5 (1997): 505. http://dx.doi.org/10.1071/c96204.

Abstract:
The title compounds (3) and (4) have been generated at low temperature by debromosilylation of 1-bromo-6-trimethylsilylbicyclo[4.1.0]hept-3-ene-2,5-dione (23) and 1a-bromo-7a-trimethylsilyl-1a,7a-dihydro-1H-cyclopropa[b]naphthalene-2,7-dione (38) respectively. Both cyclopropa-fused quinones are reactive but each could be trapped with furan to give a pair of cycloadducts, which were remarkably resistant to cycloreversion. In the absence of added trapping agent, the cyclopropanaphthoquinone (4) was intercepted by fluoride ion to give 1a-fluoro-1a,7a-dihydro-1H-cyclopropa[b]naphthalene-2,7-dione

Abstract:
The (1α,2β,3α,6α)-2,3,7,7-tetrahalobicyclo[4.1.0]heptanes (8a-c), whose structures have been determined by X-ray methods, give 2-halobicyclo[4.1.0]hepta-1,3,5-trienes (5) upon dehydrohalogenation. The 'mixed' halide (8c) and partly labelled [7-13c]-(8b,c) have revealed the presence of competing pathways in these conversions. By comparison, dehydrohalogenations of the (1α,3α,4β,6α)-3,4,7,7-tetrahalobicyclo[4.1.0]heptanes (3) give unrearranged 3-halobicyclo[4.1.0]-hepta-1,3,5-trienes (4).

Abstract:
Novel class of the carbocyclic nucleosides based on bicyclo[2.2.1]heptene/heptane was prepared by two approaches. Thymine analogues were synthesized starting from methyl (1R*,4S*)-bicyclo[2.2.1]hepta-2,5-diene-2-carboxylate1by Michael addition of the thymine salt to the double bond as the key step. The yield and ratio of the isomers of this reaction depended on the used base (DBU, K2CO3). Purine nucleoside analogues were synthesized by the linear synthesis, the purine nucleobase was build-up on the amino group.

Abstract:
Hepta-O-acetyl-O-α-D-Rhap-(1 → 3)-O-α-D-Rhap-(1 → 2)-glycerol (5) was the major component derived by way of Smith degradation of A-band polysaccharide (a D-rhamnan isolated from a mutant, AK1401, of Pseudomonas aeruginosa strain PAO1). The structure has been verified by an unambiguous synthesis of 5. Based on mass spectrometric evidence, hepta-O-acetyl-O-Ribp-(1 → 3)-O-α-D-Rhap-(1 → 2)-glycerol is considered to be one of the minor components. The Smith degradation of A-band polysaccharide and the synthesis of 5 are reported.

Abstract:
Retrocyclin RC-101, a &#952;-defensin with lectin-like properties, potently inhibits infection by many HIV-1 subtypes by binding to the heptad repeat (HR)-2 region of gp41 and preventing six-helix bundle formation. In the present study, we used in silico computational exploration to identify residues of HR2 that interacted with RC-101 and then analyzed the HIV-1 Sequence Database at LANL for residue variations in the HR1 and HR2 segments that could plausibly impart in vivo resistance. Docking RC-101 to gp41 peptides in silico confirmed its strong preference for HR2 over HR1, and implicated res
