A survey of cpDNA restriction-site variation for 22 species representing five of the six subfamilies of the palm family was conducted. Phylogenetic reconstructions based on the restriction-site data are in general agreement with conventional analyses based on morphological characters. Base-substitution estimates, derived from the restriction-site data,… (More)
We discuss a molecular dynamics study of the alanine dipeptide at the interface between water and a glycerol-l-monooleate (GMO) bilayer. The dipeptide is interfacially active and incorporates into the bilayer without disrupting its structure. The interfacial region that is readily penetrated by the dipeptide spans the entire head group portion of the… (More)
We report the first racemic and stereoselective synthesis of cis- and trans-N-alkylaziridines viaN-chloroamines; using this methodology an N-3,4,5-trimethoxybenzylaziridine was synthesised and efficiently cleaved, affording the corresponding NH aziridine in high yield.
An efficient protocol for the synthesis of structurally diverse (diphenylphosphinoylmethyl)benzenes is described. The reaction employs readily available carboxylic acids, chlorodiphenylphosphine, and water as the reagents. A 97% reduction in the reaction times and substantially higher yields of products result, up to a 60% increase, if the reactions are… (More)
This paper describes a unique application of the fluoronium cation (F+) as an organocatalyst for mediating the reaction between N-substituted imines and ethyl diazoacetate affording excellent yields of N-substituted aziridines.
We report for the first time that after O-acylation the conjugate addition products of (S)-N-(alpha-methylbenzyl)hydroxylamine undergo an efficient diastereoselective 3-exo-tet ring-closure reaction affording 2- and 2,3-disubstituted-N-alkylaziridines in good to excellent yields.
