Journal ArticleDOI
A cyclopropanol approach to the synthesis of the C13–C21 fragment of epothilones from diethyl (S)-malate
TL;DR: In this paper, the synthesis of the C13-C21 epothilone fragment using cyclopropanation of the ethoxycarbonyl groups in O-THP protected diethyl (S)-malate with ethylmagnesium bromide in the presence of titanium(IV) isopropoxide followed by site-selective cycloprocessane cleavage was performed.
Journal ArticleDOI
Stereoselective total synthesis of (–)-pumiliotoxin C by an aqueous intramolecular acylnitroso Diels–Alder approach
TL;DR: A chiral approach to (pumiliotoxin C) based on an aqueous intramolecular acylnitroso Diels-Alder reaction is described in this paper.
Journal ArticleDOI
Determination of Absolute Configuration of Secondary Alcohols Using Thin-Layer Chromatography
TL;DR: A new implementation of the competing enantioselective conversion (CEC) method was developed to qualitatively determine the absolute configuration of enantioenriched secondary alcohols using thin-layer chromatography.
Journal ArticleDOI
Enantioselective epoxidation of an allylic alcohol catalyzed by (acetylacetonato)-(l-N-methylprolinol)dioxomolybdenum. The decrease of enantioselectivity with chemical conversion
TL;DR: In this paper, it is shown that 3-methyl-3-buten-1-ol with cumene hydroperoxide catalyzed by MoO2 (acac)2 in the presence of l -N-methylprolinol yields epoxy alcohol of 50% optical purity at relatively low conversions.

Use of automated capillary column radio gas chromatography in the identification of insect juvenile hormones
TL;DR: Automated capillary column radio gas chromatography used in conjunction with high-resolution liquid chromatography has been used for the identification of biosynthesised insect hormones and their immediate precursors.
