Full textSpiroketals are widely occurring substructures in natural products. The ever-increasing range of pharmacological activities displayed by products containing spiroketals has triggered an intense interest in their study, both from a synthetic and biological aspect. The development in our laboratory of an original enol ether synthesis motivated us to prepare the spiroketal fragment of bistramide A and, subsequently, to undertake its total synthesis. Bistramide A is a biologically active molecule isolated from the marine ascidian Lissoclinum bistratum that has emerged as a potential anti-inflammatory and anti-tumoral agent based on its high cytotoxicity and potent antiproliferative effect. The [6,6] spiroketal ring system of the natural product was accessed using a modification of the Julia olefination, extended to the reaction between a lactone and a heteroarylsulfone to prepare an exocyclic enol ether. The lactone and sulfone precursors were synthesized from a common starting material, dicyclohexylidene-D-mannitol. Bistramide A and two of its analogs were prepared by functionalization of the spiroketal side chains, followed by coupling reactions with the amino acid and tetrahydropyran subunits prepared by the groups of Pr. Yli-Kauhaluoma and Pr. Piva, respectively. An alternative approach to the precursor of the tetrahydropyran system from the chiral pool was developed. Biological studies revealed interesting effects on cellular differentiation, apoptosis, and cytokinesis. Application of our methodology to the synthesis of SPIKET and studies towards the [5,6] spiroketal of attenol A, gave us the opportunity to extend the scope of our exocyclic enol ether methodology

Full textThe aim of this work was first to develop straightforward methodologies to synthesize tetrahydropyrans in order to make libraries of analogues of the C1-C13 fragment of bistramide A (north part). The efficiency of the synthetic approaches was illustrated by the use of sequential tandem processes involving a cross metathesis reaction. By this way, different types of 2,6-disubstituted analogues were obtained by oxa-Michael reaction, SN2’ reaction and haloetherification. Furthermore, the use of the Prins reaction enabled to reach 2,4,6-trisubstituted tetrahydropyrans. In the meantime, these methodologies were applied to the stereoselective synthesis of the north part of bistramide A and to the diastereocontr olled synthesis of diospongin A, another natural product

Full textSpiroketals are often found as structural subunits of many biologically active natural compounds. One of the more powerful methods to access this structure is the acid-catalyzed cyclization of enol ethers. The reaction of Julia-Kocienski reagents with lactones allows us to synthesize various tri- and tetrasubstituted exo-glycals and exo-cyclic enol ethers. It is possible to obtain preferentially either one or the other of the two diastereoisomeric enol ethers by varrying the heterocycle moiety of the sulfone. These enol éthers are cyclized under thermodynamic conditions leading to the more stable [6.6]-spiroketal but other conditions may allow us to obtain the kineticisomer. Thermodynamic spiroketals were used in total synthesis. For example, both fragments ofBroussonetine H (one iminosugar and one spiroketal) have been readily and effectively prepared.Finally, diversely substituted spiroketals have been synthesized to prepare analogues of Bistramide A.This marine metabolite is a powerful antitumor agent that binds to actin and thus blocks cell divisionalthough some interactions involving PKC-TM are actually under study
