Ethynylogization of a coarctate fragmentation.

Chemistry (Weinheim an der Bergstrasse, Germany)

Herges R, Geuenich D, Bucher G, Tonshoff C.
PMID: 10785808
Chemistry. 2000 Apr 03;6(7):1224-8. doi: 10.1002/(sici)1521-3765(20000403)6:7<1224::aid-chem1224>3.3.co;2-8.

Coarctate reactions form a separate class of elementary closed-shell processes in addition to polar and pericyclic reactions. Hence, they also follow a different homology principle. Whereas vinylogous polar and pericyclic reactions differ in the length of the reacting system...

The synthesis of 2,3-R(2)-9,10-(OMe)(2)-substituted pentacenes (R=OMe, F, Br, CN; 1-4) from 2,3-R(2)-9,10-dimethoxy-6,13-dihydro-6,13-ethanopentacene-15,16-diones (α-diketone-bridged precursors) by photochemically induced bis-decarbonylation (Strating-Zwanenburg reaction) is described. Under matrix-isolation conditions (solid Ar, 10 K) the S(1) transitions of 1 and 2 undergo hypsochromic and...

The doping of graphene molecules by borazine (B(3)N(3)) units may modify the electronic properties favorably. Therefore, the influence of the substitution of the central benzene ring of hexa-peri-hexabenzocoronene (HBC, C(42)H(18)) by an isoelectronic B(3)N(3) ring resulting in C(36)B(3)N(3)H(18) (B3N3HBC)...

Pediatric transplantation

Zierhut H, Kanzelmeyer N, Buescher A, Höcker B, Mauz-Körholz C, Tönshoff B, Metzler M, Pohl M, Pape L, Maecker-Kolhoff B.
PMID: 34021949
Pediatr Transplant. 2021 Sep;25(6):e14042. doi: 10.1111/petr.14042. Epub 2021 May 22.

BACKGROUND: Post-transplant lymphoproliferative disease (PTLD) is a life-threatening complication in renal transplant recipients. Immunomodulatory and chemotherapeutic treatment potentially affect allograft function. The aim of this study was to evaluate graft function of pediatric kidney transplant recipients following diagnosis and...
