The aglucone of sinigrin
The mechanism of the ascorbate-activated cleavage of sinigrin to mustard oil has been postulated as enzymatic hydrolysis of the thioglucoside to the aglucone, which undergoes spontaneous Lossen rearrangement to allyl ...
Ionization and dissociation studies of propadiene, 1, 3-butadiene, 1,3 trans-pentadiene, 2,4-hexadiene and 2,5-dimethyl-2,4-hexadiene by electron impact
The ionization and dissociation of propadiene, 1,3-butadiene, 1,3-trans-pentadiene, 2,4-hexadiene and 2,5-dimethy1-2,4-hexadiene have been studied using a CEC-21-701 mass spectrometer. The ionization potentials measured ...
Phenolate radical coupling as a method of triterpene synthesis
The dienone [B] is a possible precursor for the synthesis of tetra- and pentacyclic triterpenes. In this investigation a synthesis of the dimeric phenol [A] and the conversion of [A] to [B] by a phenolate radical coupling ...
