In the crystal of the title compound, C(8)H(8)O(3)S, the mol-ecules are linked into a three-dimensional array by inter-molecular C-H⋯O hydrogen bonds.

Two aldehyde dehydrogenases involved in the degradation of toluene and xylenes, namely, benzaldehyde dehydrogenase and 2-hydroxymuconic semialdehyde dehydrogenase, are encoded by the xylC and xylG genes, respectively, on TOL plasmid pWW0 of Pseudomonas putida. The nucleotide sequence of xylC was determined in this study. A protein exhibiting benzaldehyde dehydrogenase activity had been purified...

In the title compound, C(19)H(15)NO, the N atom adopts an approximately trigonal-planar geometry, lying 0.07 (1) Å from the plane defined by its three neighbouring C atoms. The two phenyl rings and the benzaldehyde group form dihedral angles of 53.0 (1)/47.2 (1) and 29.0 (1)°, respectively, with this central plane.

In the title compound, C(8)H(9)N(3)S·H(2)O, intra-molecular N-H⋯N hydrogen bonding contributes to the mol-ecular conformation. Water mol-ecules are involved in inter-molecular N-H⋯O and O-H⋯S hydrogen bonds, which link the mol-ecules into ribbons extended along the a axis. Weak inter-molecular N-H⋯S hydrogen bonds link these ribbons into layers parallel to the ab plane with the phenyl rings poi...

The title compound, C(14)H(12)O(2), has an essentially planar conformation with the two aromatic rings forming a dihedral angle of 5.23 (9)° and the aldehyde group lying in the plane of its aromatic group [maximum deviation = 0.204 (3) Å]. Weak inter-molecular C-H⋯O contacts are found to be shortest between the aldehyde O-atom acceptor and the H atoms of the methyl-ene group.

In the title compound, C(14)H(13)NO, the dihedral angle between the aromatic rings is 66.08 (9)°. Chains are formed along the b axis through inter-molecular N-H⋯O hydrogen bonds. The crystal structure is further stabilized by C-H⋯π inter-actions.

Carbon-carbon triple bonds of alkynes are ubiquitous. They serve as valuable starting materials that can be transformed into a vast array of diverse materials, with applications ranging from medicinal chemistry to electronic materials. The methods used to prepare alkynes involve stoichiometric reactions and the most popular install only a single carbon rather than uniting larger fragments. Thes...

The relative configurations of tert-butyldimethylsilyl (TBDMS) ethers of all four diastereomers of the aldols of tropinone (8-methyl-8-azabicyclo[3.2.1]octan-3-one), as well as of granatanone (9-methyl-9-azabicyclo[3.3.1]nonan-3-one), were determined from NMR data, and from the observed interconversion of the diastereomers (exo,anti to endo,syn and exo,syn to endo,anti). The exo forms invert to...

Meldrum's acid, 2'5-diphenyl-1'3-dioxane-4'6-dione, was produced by [2+2] cycloadditions of the (chlorocarbony1)phenylketene with benzaldehyde. Acid hydrolysis of the meldrum's acid regenerated benzaldehyde and also yielded phenylacetic acid as the final product
