We show how to construct semi-bent Boolean functions from PSaplike bent functions. We derive infinite classes of semi-bent functions in even dimension having multiple trace terms.

The double Bingel reaction of fullerene C60 with bismalonates attached to a Tröger base derived tether afforded trans-1, trans-2, trans-3, and trans-4 bisadducts with excellent regioselectivity. In particular, enantiomerically pure bisadducts with inherently chiral trans-2 or trans-3 addition patterns were prepared starting from enantiomerically pure bismalonates. The absolute configuration of ...

In the crystal structure of the title compound, C(15)H(17)NO(2)S, the conformations of the N-C bond in the C-SO(2)-NH-C segment are trans and gauche, respectively, with respect to the S=O bonds. The mol-ecule is bent at the S atom with a C-SO(2)-NH-C torsion angle of -61.8 (2)°. Furthermore, the conformation of the N-H bond and the 3-methyl group in the aniline benzene ring are nearly anti to e...

The discovery of photoswitchable azobenzene-systems that undergo trans-to-cis photoisomerisation was a milestone in supramolecular chemistry. Such photoswitches have possible applications in data storage, stimuli responsive delivery systems, and molecular machines due to fast and selective switching. However, the light induced cis isomer of azobenzene is rather unstable and reverts thermally an...

[reaction: see text] An efficient synthesis of enone 4, representing the ABC ring motif of norzoanthamine, is presented. The crucial C22 quaternary center was introduced via a stereoselective methylation of enone 8. The trans-anti-trans relative configuration of the ABC framework of 4 was installed via a sequence of reactions that included a hydroboration and a modified Robinson annulation.

In the crystal structure of the title compound, C(14)H(13)Cl(2)NO(2)S, the configurations of the N-C bond with respect to the S=O bonds are trans and gauche. The mol-ecule is bent at the S atom with a C-SO(2)-NH-C torsion angle of -69.7 (2)°. The conformation of the N-H bond is syn to the 3-chloro group in the substituted aniline ring. The two benzene rings are tilted with respect to each other...

The palladium-catalyzed intramolecular coupling of allyl stannanes with allyl carboxylates provides a general synthesis of five- and six-membered-ring carbocycles. The intramolecular coupling leads selectively to trans five-membered carbocycles and cis six-membered carbocycles, regardless of the cis or trans configuration of the allylic functions in the starting material. For example, the stere...

In the crystal structure of the title compound, C(13)H(11)Cl(2)NO(2)S, the conformations of the N-C bond in the C-SO(2)-NH-C segment are trans and gauche with respect to the S=O bonds. The C-S(O(2))-N(H)-C torsion angle is 74.8 (4)°, indicating that the mol-ecule is bent at the S atom. In the crystal structure, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur. An intramolecular N-...
