Abstract
Hexabenzylhexaazaisowurtzitane is converted to tetracetyl, dibenzyl azaisowurtzitane. The benzyl groups are removed by catalytic transfer hydrogenolysis leaving a pair of available nitrogens. The available nitrogens are acetylated, and the resulting intermediate is converted to CL-20 with a strong nitrating agent.
