(18-Crown-6)-2,3,11,12-tetracarboxylic acid is an excellent chiral NMR solvating agent for cyclic β-amino acids with cyclopentane, cyclohexane, cycloheptane, cyclopentene, cyclohexene, bicyclo[2.2.1]heptane, and bicyclo[2.2.1]heptene rings. The crown ether was added to the neutral β-amino acids in methanol-d4. A neutralization reaction between the crown ether and β-amino acid forms the ammonium ion needed for

A total and versatilesynthesis of a new series of carbocyclic nucleosideanalogues which are derivatives of purine with a 1,2-disubstituted cyclopentene ring (I) is described. The 6-chloropurine derivatives 3 and 9 were prepared by construction of the heterocyclic base about the primary amino group of the (±)-cis-2-amino-3-cyclopentenylmethanol (1), which was synthesized in good yield from cyclopentadiene

The synthesis of a new series of 1,2-disubstituted carbonucleoside analogues, pyrimidines of general structure I, is reported. These compounds were prepared in good yield from (′)-6-azabicyclo[3.2.0]hept-3-en-7-one (1) via two synthetic routes that involve NaBH 4 -mediated C-N bond cleavage as the key step. The uracil derivative Ia was halogenated with Cl, Br, and I at position 5 by treatment with
