5-[(tert-Butyl-diphenyl-sil-yloxy)meth-yl]pyridazin-3(2H)-one.

ABSTRACT: In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C-C-O-Si torsion angle is -140.69?(17)°. In the crystal, mol-ecules are linked by pairs of strong N-H?O hydrogen bonds into centrosymmetric dimers with graph-set notation R 2 (2)(8). Weak C-H?? inter-actions are also observed.

Project description:In the title compound, C21H24N2O2Si, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether group are placed toward opposite sides and the tert-butyl and pyridazinone moieties are anti-oriented across the Si-O bond [torsion angle = -168.44?(19)°]. In the crystal, mol-ecules are assembled into inversion dimers through co-operative N-H?O hydrogen bonds between the NH groups and O atoms of the pyridazinone rings of neighbouring mol-ecules. The dimers are linked by ?-? inter-actions involving adjacent pyridazinone rings [centroid-centroid distance = 3.8095?(19)?Å], generating ladder-like chains along the b-axis direction. The chains are further linked into a two-dimensional network parallel to the ab plane through weak C-H?? inter-actions.

7-(tert-Butyl-diphenyl-sil-yloxy)-2,2-dimethyl-1-benzofuran-3(2H)-one.

Project description:The title compound, C(26)H(28)O(3)Si, is an allylic oxidation product of the tert-but-yl(2,2-dimethyl-2,3-dihydro-benzo-furan-7-yl-oxy)diphenyl-silane with N-bromo-succinimide and 2,2'-azobis-isobutyronitrile. The nine-atom bicyclic system is almost planar, with an r.m.s deviation of 0.0123 (2) Å and a maximum deviation of 0.031 (2) Å for the O atom. In the crystal, the mol-ecules pile up along the b axis but the strongest inter-molecular contacts are the π-π stacking inter-actions between the benzene rings along the c axis [centroid-centroid distance = 3.655 (3) Å].

4-[(tert-Butyl-dimethyl-sil-yl)-oxy]-6-meth-oxy-7-methyl-5-(oxiran-2-ylmeth-yl)-2-benzofuran-3(1H)-one.

Project description:The title compound, C(19)H(28)O(5)Si, was obtained in the reaction of 1,3-dihydro-4-[(tert-butyl-dimethyl-sil-yl)-oxy]-6-meth-oxy-7-methyl-3-oxo-5-(prop-2-en-yl)isobenzofuran with meta-chloro-perbenzoic acid. This reaction is one of the stages of the total synthesis of mycophenolic acid, which we attempted to modify. The title compound forms crystals with only weak inter-molecular inter-actions. The strongest stacking inter-action is found between the benzene and furan rings of inversion-related mol-ecules with a distance of 3.8773 (13) Å between the ring centroids.

1,1'-Bis(tert-butyl-dimethyl-sil-yl)ferrocene.

Project description:The asymmetric unit of the title compound, [Fe(C11H19Si)2], consists of one half of a ferrocene derivative. The Fe(II) atom lies on a twofold rotation axis, giving an eclipsed conformation for the cyclo-penta-dienyl ligands. No significant inter-molecular inter-actions are observed in the crystal structure.

Project description:The title compound, C(30)H(30)N(4)O(2), has a non-planar conformation, the dihedral angles formed by the pyridazinone ring plane and the three phenyl rings being 54.61 (7), 51.10 (7) and 59.53 (8)°. The piperazine ring adopts a chair conformation. Inter- and intra-molecular C-H⋯O contacts are found in the crystal structure and these consolidate the three-dimensional packing.

(±)-1-{8'-(tert-Butyl-diphenyl-silyloxy-meth-yl)-1',7'-dioxaspiro-[5.5]undecan-2'-yl}uridine.

Project description:The crystal structure of the title compound, C(30)H(38)N(2)O(5)Si, has been investigated to establish the relative stereochemistry at the spiro ring junction and the two anomeric centres. Each of the O atoms in the tetra-hydro-pyran rings adopts an axial position on the neighbouring ring. This bis--diaxial conformation is adopted, thus gaining maximum stablization from the anomeric effect. The silyl-protected hydroxy-methyl and uracil substituents adopt equatorial positions on their associated tetra-hydro-pyran rings, thereby minimizing unfavourable steric inter-actions. The dimeric (2'R*,6'R*,8'R*)- and (2'S*,6'S*,8'S*)-uridine units are connected to each other across crystallographic inversion centres via inter-molecular N-H⋯O hydrogen bonds.

6-[(tert-Butyl-dimethyl-sil-yl)-oxy]-3-ethenyl-7-meth-oxy-4-[(tri-methyl-sil-yl)ethyn-yl]naphtho-[2,3-c]furan-1(3H)-one.

Project description:The tricyclic core in the title compound, C26H34O4Si2, shows disorder of the furan ring and deviates slightly from planarity, with the largest displacement from the least-squares plane [0.166 (2) Å] for the major disordered part of the methine C atom. To this C atom the likewise disordered vinyl group is attached, lying nearly perpendicular to the tricyclic core. In the crystal, mutual C-H⋯π inter-actions between the methine group of the furan ring and the central ring of the tricyclic core of an adjacent mol-ecule lead to inversion-related dimers.
