Synthesis of a recently discovered S-methylated quinolone natural product (1) was carried out, in addition to the production of a range of 2-substituted 4-quinolone derivatives (2–11). Two approaches were used: (i) the base-catalyzed cyclization of N-(ketoaryl)amides; (ii) attachment of the substituent to the quinolone core via a Suzuki–Miyaura cross-coupling. Also produced were a small suite of related

report a new, short and stereocontrolled synthesis of two constrained nucleosides analogues, 1',2'- methano-2',3'-dideoxyuridine 9, and the corresponding cytidine analog 12. X-ray crystallography revealed that the furanose ring in the constrained uridine and cytidine analogues was flattened with virtual loss of pseudorotation. The phosphoramidate esters of the novel constrained uridine and cytidine nucleosides

Carbocyclic polyoxin C (2) and its alpha-epimer 3 were synthesized in racemic form in an efficient and diastereodivergent fashion from cis-4-(N-tert-butylcarbamoyl)cyclopent-2-en-1-ol (5a). This synthesis features a Pd(0)-catalyzed substitution reaction, a novel, mild reduction of an alpha-nitro ester to an amino acid ester, and an improved procedure for uracil ring formation.
(±)-<i>erythro</i>-γ,δ-Dihydroxycarboxylic Acid Lactones from a β-Lithiopropionate Equivalent and α-Chloroaldehydes

Reaction of β-ethylthio-β-lithioacrylate 1A with α-chloroaldehydes furnished predominantly the erythro products 3, which were isolated as γ-lactones 4. At room temperature intermediates 3 are transformed into the (±)-erythro-γ,δ-dihydroxycarboxylic acid γ-lactones 8. Raney nickel treatment provided interesting natural γ-lactone derivatives; thus, from erythro-8c the socalled L-factor erythro-9c was obtained. Similarly, from β-methoxy β-lithioacrylate 10A the (±)-erythro-γ,δ-dihydroxycarboxylic acid δ-lactone erythro-11 was gained.
