A Novel Approach to the CDE Ring System of Pectenotoxin-4 Triggered by VO(acac)₂-Induced Epoxy-Acetalization

, 2016
A novel approach to the CDE fragment of pectenotoxin-4 is described wherein the bicyclic acetal is constructed via a cascade cyclization induced by VO(acac)2 epoxidation of a homoallylic ...

Studies on the Synthesis of Pectenotoxin II:  Synthesis of a C(11)−C(26) Fragment Precursor via [3 + 2]-Annulation Reactions of Chiral Allylsilanes

, 2016
A synthesis of tetracycle 2 corresponding to the C(11)−C(26) fragment of pectenotoxin II is described. The synthesis features two highly stereoselective [3 + 2]-annulation reactions of chiral allylsilanes, generated via allylboration of aldehydes with ...

Mass spectrometic analysis of the marine lipophilic biotoxins pectenotoxin-2 and okadaic acid by four different types of mass spectrometers

, 2008
The performances of four different mass spectrometers [triple-quadrupole (TQ), time-of-flight (ToF), quadrupole ToF (Q-ToF) and ion trap (IT)] for the detection of the marine lipophilic toxins pectenotoxin-2 (PTX2) and okadaic acid (OA) were investigated.
