A simple and general method for the synthesis of highly substituted α-tropolone ethers that allows rapid access to the bis(tropolone) core of the antiproliferative metabolites (-)-gukulenins A and F (3, 4) is described. The reaction proceeds by thermolyti

Ionic liquid supported on magnetic nanoparticles as highly efficient and recyclable catalyst for the synthesis of β-keto enol ethers

A magnetically ionic liquid supported on γ-Fe2O 3 nanocatalyst (AlxCly-IL-SiO 2γ-Fe2O3) was synthesized and evaluated as a recoverable catalyst for the synthesis of β-keto enol ethers. The immobilized catalyst proved to be effective and provided the products in high to excellent yield at room temperature. Moreover, the catalyst could be easily recovered by magnetic separation and recycled for six times without significant loss of its catalytic activity.

Asymmetric synthesis of O-protected acyloins using enoate reductases: Stereochemical control through protecting group modification

O-Protected cyclic acyloins were obtained in nonracemic form through asymmetric bioreduction of α,β-unsaturated alkoxy ketones by using 11 different enoate reductases from the "Old Yellow Enzyme" family. The stereochemical outcome of the biotransformation could be switched by variation of the O-protecting group or by the ring size of the substrate, which allows access to both stereoisomers in up to >97 % ee Whereas α-alkoxy enones were readily accepted as substrates, β-analogs were not converted. Overall, α-alkoxy enones represent a novel type of substrate for flavin-dependent ene-reductases. Copyright

Synthetic studies toward sordarin: Building blocks for the terpenoid core and for analogues thereof

Avenues to bi- and tricyclic building blocks for the elaboration of sordaricin and its analogues are described. The target molecules were obtained through inter- and intramolecular Diels-Alder reactions of a number of previously unknown cyclopentadienes. Unusual properties of 3-cyanoenones and 1-cyanocyclopen-tadienes have been unveiled and circumvented.

An avenue to the sordarin core adaptable to analog synthesis

We describe a synthesis of ketones 3 (X = O-R or CN; Y = H or alkyl), which are useful building blocks for the preparation of analogs of the potent antifungal agent sordarin, 1. Congeners of 1 constructed from 3 should permit detailed SAR investigations of the terpenoid core of the natural product.
