In this paper, we attempt to investigate the connection between various types of ideals (for examples $(m, n)$-ideal, bi-ideal, interior ideal, quasi ideal, prime ideal and maximal ideal) of an ordered semigroup $(S,cdot ,leq)$ and the correspond hyperideals of its EL-hyperstructure $(S,*)$ (if exists). Moreover, we construct the class of EL-$Gamma$-semihypergroup associated to a partially orde...

The front cover picture was designed by C. Zippel, Z. Hassan and S. Bräse. Kinetic resolution of 4-acetyl[2.2] paracyclophane via ruthenium-catalyzed enantioselective hydrogenation has been realized. This method can be performed on a multigram-scale gives access to enantiomerically pure derivatives with planar central chirality (Rp)-4-acetyl-PCP (97% ee, 43%) (Sp,S)-PCP 46%), which are useful i...
