In the title compound, C21H32N4O4, no disorder is present in the 15-membered hydro-carbon ring, which exists in an unsymmetrical quinquangular [12345] conformation. The 2,4-dinitro-phenyl-hydrazone group is approximately perpendicular to the C15 ring, with a dihedral angle of 84.66 (1)° between their best planes.

The activated Me2SO reagent , 'Swern reagent'> oxidises the trimethylsilyl ethers of primary and secondary alcohols directly to the corresponding carbonyl compound.Useful selectivity is possible where competing ether groups possess large differences of steric hindrance.Dimethyl-t-butylsilyl ethers are unaffected by this reagent.
