Diasterodivergent synthesis of fused ring systems by Kiss, E

“…We believed that the configurational lability of 6π systems could be reduced by constraining them within a ring system.</p> <p><b>Results and Discussion</b></p> <p>En route to the synthesis of a starting material for the transannular electrocyclisation reaction, we noticed that a 5-5-3 fused ring system had formed, in one step, from a linear precursor and as a single diastereomer. …”

Electrosynthesis of buckyballs with fused-ring systems from PCBM and its analogue by Wei-Feng Wang, Kai-Qing Liu, Chuang Niu, Yun-Shu Wang, Yang-Rong Yao, Zheng-Chun Yin, Muqing Chen, Shi-Qi Ye, Shangfeng Yang, Guan-Wu Wang

“…Herein, electrosynthesis of buckyballs with fused-ring systems has been achieved through radical α-C−H functionalization of the side-chain ester for both PCBM and its analogue, [6,6]-phenyl-C61-propionic acid methyl ester (PCPM), in the presence of a trace amount of oxygen. …”

Dragging of inertial frames in the composed Kerr-Newman-orbiting-ring system by Shahar Hod

“…In order to address this important question, in the present compact paper we explore the physical phenomenon of dragging of inertial frames by an orbiting ring in the composed Kerr-Newman-black-hole-orbiting-ring system. In particular, using analytical techniques, we reveal the fact that in this composed two-body (black-hole-ring) system the quantity ΔΩH has an explicit non-trivial functional dependence on the angular momentum JH of the central spinning black hole.…”
