(E)-tert-Butyl 4-(N′-hydroxycarbamimidoyl)piperazine-1-carboxylate
In the title compound, C10H20N4O3, the piperazine ring adopts a chair conformation. The mol-ecule adopts an E conformation across the C=N double bond, with the -OH group and the piperazine ring trans to one another. Further, the H atom of the hy-droxy group is directed away from the NH2 group. An intra-molecular N-H⋯O contact occurs involving the NH2 group and the oxime O atom. In the crystal, ...

In the title compound, C(9)H(14)BNO(4), the carbonyl and boronic acid groups are essentially coplanar with the pyrrole ring and the boronic acid group has an exo-endo conformation. The exo-oriented OH is engaged in an intra-molecular O-H⋯O inter-action, while the endo-oriented one is involved in inter-molecular hydrogen bonding to form centrosymmetric dimers. A supra-molecular assembly is achie...
متن کاملSynthesis and Molecular Structure of tert-Butyl 4-(2-tert-butoxy-2-oxoethyl)piperazine-1-carboxylate
The crystal and molecular structure of tert-butyl 4-(2-tert-butoxy-2-oxoethyl)piperazine-1-carboxylate is reported. The title compound crystallizes from a petroleum ether/ethyl acetate mixture in the monoclinic space group P 21/c with four molecules in the unit cell. The unit cell parameters are: a = 8.4007(2) Å, b = 16.4716(4) Å, c = 12.4876(3) Å; β = 90.948(1)° and V = 1727.71(7) Å. Bond leng...
متن کاملtert-Butyl N-((1S)-2-hydroxy-1-{N′-[(E)-2-hydroxy-4-methoxybenzylidene]hydrazinecarbonyl}ethyl)carbamate
The mol-ecule of the title compound, C(16)H(23)N(3)O(6), is twisted about the chiral C atom with the dihedral angle formed between the amide residues being 76.9 (3)°. Overall, the mol-ecule is curved with the terminal organic groups lying to the same side. The conformation about the imine bond [1.291 (5) Å] is E and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, ...
متن کاملtert-Butyl N-{4-[N-(4-hydroxyphenyl)carbamoyl]benzyl}carbamate
In the title compound, C(19)H(22)N(2)O(4), the dihedral angle between the aromatic rings is 67.33 (2)°. In the crystal, mol-ecules are linked through N-H⋯O and O-H⋯O hydrogen bonds, generating a two-dimensional network lying parallel to (100). As a result of the twist of the mol-ecular skeleton and the hindrance of the tert-butyl groups, no π-π inter-actions exist between the aromatic rings.
