tert-Butyl 3-[N-(tert-butoxycarbonyl)methylamino]-4-methoxyimino-3-methylpiperidine-1-carboxylate
The title compound, C(18)H(33)N(3)O(5), was prepared from N-tert-butoxy-carbonyl-4-piperidone using a nine-step reaction, including condensation, methyl-ation, oximation, hydrolysis, esterification, ammonolysis, Hoffmann degradation, tert-butoxy-carbonyl protection and methyl-ation. The E configuration of the methyl-oxime geometry of the compound is confirmed.

The title compound, C(12)H(16)O(2), is approximately planar (r.m.s. deviation = 0.030 Å), apart from two methyl groups of the tert-butyl unit [deviations of the C atoms = 1.140 (2) and -1.367 (1) Å]. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into hexa-meric rings with R(6) (6)(48) graph-set motifs.

In the title compound, C(16)H(25)NO, the N-tert-butyl-propanamide fragment is essentially planar, with the exception of two C atoms of the tert-butyl group (r.m.s. deviation = 0.005 Å), forming a dihedral angle of 84.09 (10)° with the plane of the mesityl fragment (r.m.s. deviation = 0.002 Å). The crystal packing is stabilized by an inter-molecular N-H⋯O hydrogen bond, which links the mol-ecule...

The title compound, C(13)H(23)N(3)O(4), was prepared starting from ethyl N-benzyl-3-oxopiperidine-4-carboxyl-ate through a nine-step reaction, including hydrogenation, Boc (tert-butoxy-carbon-yl) protection, methyl-ation, oximation, hydrolysis, esterification and ammonolysis. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds to form a porous three-dimension...
