1,2-Bis(p-phenylcarbamoyl-oxy-amino-cyclohexylidene)ethane

4-Amino-12-methyl­sulfon­yloxy-[2.2]para­cyclo­phane

The title compound, C17H19NO3S, was synthesized from 4-benzhydryl-idene-amino-12-hy-droxy-[2.2]para-cyclo-phane and methane-sulfonyl chloride. In the mol-ecule, the distance between the centroids of two aromatic rings is 2.960 (5) Å. In the crystal, weak N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to the ac plane.

Methyl ({[(4E)-1,3-dimethyl-2,6-di­phenyl­piperidin-4-yl­idene]amino}­oxy)acetate

In the title compound, C22H26N2O3, the piperidine ring exhibits a chair conformation. The phenyl rings attached to the piperidine at the 2- and 6-positions have axial orientations. These rings make a dihedral angle of 49.75 (11)°. The amino-oxy acetate group attached at the 4-position has an equatorial orientation. In the crystal, inversion dimers linked by pairs of C-H⋯π inter-actions occur.

Highly regio- and enantioselective multiple oxy- and amino-functionalizations of alkenes by modular cascade biocatalysis

New types of asymmetric functionalizations of alkenes are highly desirable for chemical synthesis. Here, we develop three novel types of regio- and enantioselective multiple oxy- and amino-functionalizations of terminal alkenes via cascade biocatalysis to produce chiral α-hydroxy acids, 1,2-amino alcohols and α-amino acids, respectively. Basic enzyme modules 1-4 are developed to convert alkenes...

Oxy-coal Combustion Studies

Synthetic routes to, transformations of, and rather surprising stabilities of (N-methyl-N-phenylcarbamoyl)sulfenyl chloride, ((N-methyl-N-phenylcarbamoyl)dithio)carbonyl chloride, and related compounds.

The title compound classes, (carbamoyl)sulfenyl chlorides and ((carbamoyl)dithio)carbonyl chlorides, have been implicated previously as unstable, albeit trappable, intermediates in organosulfur chemistry. The present work reports for each of these functional groups: (i) several routes to prepare it in the N-methylaniline family; (ii) its direct structural characterization by several spectroscop...
