I think you'll need to look into 'flying capacitor' techniques, in which charge is transferred from a lower voltage rail to a higher voltage rail via a capacitor. MOS transistors are used as switches to connect the capacitor to the lower voltage, then to the higher voltage rail in sequence.
For further ideas, look at devices from Maxim and Linear Technology - these companies make several inductorless DC-DC converters.
Hope this helps,
