A cationic amphiphile for facilitating transport of a biologically active molecule into a cell has the structure A-F-D, in which A is a lipid anchor, D is a head group, and F is a spacer group having the structure described herein. A method for facilitating transport of a biologically active molecule into a cell comprises preparing a lipid mixture comprising a cationic amphiphile having structure A-F-D-, preparing a lipoplex by contacting the lipid mixture with a biologically active molecule; and contacting the lipoplex with a cell, thereby facilitating transport of the biologically active molecule into the cell.

A convenient alkene oxyamination compatible with a wide range of alkenoic acids and electron-rich amines is accomplished via aerobic copper catalysis. The synthetic value of this protocol is highlighted with the stereoselective formation of complex amino lactone products. In addition, product derivatizations to privileged nitrogen heterocycles have also been demonstrated via simple reduction methods
