A versatile synthetic platform based on strained propargyl amines
He, Zhi,Yudin, Andrei K.
supporting information; experimental part, p. 1607 - 1610 (2010/06/16)
"Chemical Equation Presented" Divergent reactivity: Various ethynylaziridines behave as strained propargyl amines and can be directly converted into unprotected α-amino allenes by a highly diastereoselective SN2′ hydride delivery (see scheme). Additional reaction routes involve chemo- and regioselective transformation into either bicyclic aziridine/ enol ethers or highly strained azirine alkynes.
Chromatographic Resolution of Enantiomers with Natural Polymers
Konrad, Gerd,Musso, Hans
, p. 1956 - 1967 (2007/10/02)
Cheap, chiral, natural polymers have been tested as stationary phases for the chromatographic resolution of the enantiomers of several very different racemates.Silk, wool, and cellulose are not suitable.Potato starch can be used well in special cases.Hesse's and Hagel's cellulose triacetate finds widest application, as shown by several new examples.This property results from a genuine chiral tertiary structure not to be destroyed during preparation.
MASS SPECTROMETRIC DECOMPOSITION OF β-PHENYLOXIRANECARBOXYLIC ESTERS

The electron-impact mass spectra of the E- and Z-isomers of the α,β-methyl substituted esters of β-phenyloxiranecarboxylic acids have been studied.
STEREOSPECIFITY OF THE SPIN-SPIN COUPLING CONSTANTS AND CHEMICAL SHIFTS IN THE 13C NMR SPECTRA OF OXIRANECARBOXYLIC ESTERS
Alekseeva, L. M.,Bokanov, A. I.,Shvedov, V. I.,Sheinker, Yu. N.

It was established that the 3JCH spin-spin coupling constants and chemical shifts in the 13C NMR spectra of the cis and trans isomers of oxiranecarboxylic esters are stereospecific.The signals for the methyl groups of the cis isomer are 4-7 ppm upfield from the signals for the trans isomer.The 3JCH constant due to spin-spin coupling of the 2-CH3 (or 3-CH3) group and the proton at the C3 (or C2) atom amounts to 2 Hz for the cis isomer and is absent for the trans isomer.
AN IMPROVED PROCEDURE FOR THE SYNTHESIS OF GLYCIDIC ESTERS

Aromatic and aliphatic aldehydes and ketones readily undergo Darzens condensation on reaction with NaH and chloroacetate in CH3CN.
