Abstract: A new cage-like dimeric nickel(II) complex Ni2L2(DMSO)4 based on a ditopic redox-active hydroxy-para-iminobenzoquinone type ligand LH2 (L is 4,4′-(1,3-phenylene-bis(azaneylylidene))- bis(3,6-di-tert-butyl-2-oxycyclohexa-2,5-dien-1-one dianion) was synthesized in ...
In a manner similar to Example 4 treat the products of Preparation V B. with 3,5-di-t-butyl-1,2-benzoquinone. Isolate each of the resultant products to obtain, respectively: 1-desamino-1-oxo-3,2',6',3"-tetra-N-acetyl-3',4'-dideoxykanamycin B, ...
2,5 - Di - NHCOR - 3,6 - diamino - 1,4 - benzoquinones, wherein R is as defined above, are prepared by acylation of 2,3,5,6-tetramino-1,4-benzoquinone. The compounds of the invention may be used in the prevention or treatment of poultry coccidosis, and may be administered in...
In order to cleave gangliosides and isolate the oligosaccharide portion, the allylic nature of OH-3 of the sphigenine base was utilized in its selective oxidation to a ketone group by 2,3-dichloro-5,6-dicyanobenzoquinone. Triethylamine treatment of the oxidation products resulted in the β-elimi...
