Synthetic studies towards pectenotoxin-2: Synthesis of the nonanomeric 10-epi-ABCDE ring segment by kinetic spiroketalization

The synthesis of the nonanomeric 10-epi-ABCDE ring system of pectenotoxin-2 has been achieved by using a kinetic spiroketalization reaction. The synthesis of the spiroketalization precursor was achieved through a cross-metathesis/ hydrogenation sequence.

Epoxidation of α,β-unsaturated esters by dimejhyldioxirane

Kinetic data for the epoxidation of a series of α,β-unsaturated esters, 2-10, by dimethyldioxirane in dried acetone are reported. These epoxidations are less sensitive to steric effects and occur with lower k 2 values than those for simple alkenes. Relative reactivity could be modeled based on a spiro transition state mechanism. The density function calculations were in good agreement with the krel values except for those compounds with cis-β-substituents.

Alternative protocol for oxidation in water: An effective epoxidation system promoted by the combination of Oxone and an amphiphilic ketone

Epoxidation of cyclooctene and other alkenes with Oxone was promoted effectively in an aqueous micellar solution of an amphiphilic ketone, which was easily derived from hepta(ethylene glycol) monodecyl ether.
