Abstract
Alkyne oxazole 11c is converted in three steps, and approximately 45% overall yield, to furanolactone 21alpha having the A,B,E-ring core of the wortmannin (2) family of furanosteroids. The TiCl4-catalyzed insertion of EtO2C-CH=O between C3 and C10 in furanoacid 14d is >98% stereoselective via a pathway involving chemoselective lactonization of equilibrating aldol intermediates 23alpha,beta (dynamic kinetic resolution).

Abstract
Analogues of farnesyl diphosphate (FPP, ) containing phenyl substituents in place of methyl groups have been prepared in syntheses that feature use of a Suzuki-Miyaura reaction as a key step. These analogues were found not to act as substrates of the sesquiterpene cyclase aristolochene synthase from Penicillium roqueforti (AS). However, they were potent competitive inhibitors of AS with K(I)-values ranging from 0.8 to 1.2 microM. These results indicate that the diphosphate group contributes the largest part to the binding of the substrate to AS and that the active sites of terpene synthases are sufficiently flexible to accommodate even substrate analogues with large substituents suggesting a potential way for the generation of non-natural terpenoids. Molecular mechanics simulations of the enzyme bound inhibitors suggested that small changes in orientations of active site residues and subtle alterations of the conformation of the backbones of the inhibitors are sufficient to accommodate the phenyl-farnesyl-diphosphates.

Abstract
The synthesis of 2,3-dideoxy-3-C-(hydroxymethyl)-3-C-methyl-D-glycero-tetrofuranosyl++ + nucleosides was accomplished in high enatiomeric purity (98.5% ee) via [3,3]-sigmatropic Claisen rearrangement of (E)(S)-5-benzyloxy-1-tert-butyldimethylsilanyloxy-4-methyl-pent-3- en-2-ol prepared from 2,3-O-isopropylidene-D-glyceraldehyde. The synthesized nucleosides were assayed against human immunodeficiency virus (HIV) and hepatitis B virus in human peripheral blood mononuclear (PBM) and 2.2.15 cells, respectively. 6-Amino-9-[2,3-dideoxy-3-C-(hydroxymethyl)-3-C-methyl-beta-D-glycero- tetrofuranosyl]-2-fluoropurine shows moderate antiviral activity (EC50 = 2.55 microM) against HIV-1 strains and 6-amino-9-[3-deoxy-3-C-(hydroxymethyl)-3-methyl-alpha-D-glycero-tetro furanosyl]-2-fluoropurine exhibits potent anti-HIV activity (EC50 = 0.073 microM) with significant cytotoxicity (IC50 = 1.0 microM).
