Objectives: While useful in diagnosing angiosarcomas, CD31 can also highlight histiocytes within soft tissue tumors and lead to errors in diagnosis. We sought to determine how often CD31 highlights cutaneous histiocytomas and histiocytoma mimics. Met

Synthesis and absolute configuration of polypropionate metabolites of siphonaria australis
Autor: Kim F. Albizati, Uma N. Sundram
Publikováno v: Tetrahedron Letters. 33:437-440
An enantioselective synthesis of a C 17 metabolite from Siphonaria australis has been accomplished. This has led to the assignment of the absolute configuration of two metabolites in this series through the use of the exciton chirality method.

Synthesis and absolute configuration of the antiparasitic furanosesquiterpenes (-)-furodysin and (-)-furodysinin. Camphor as a six-membered ring chiral pool template
Autor: Valerie A. Vaillancourt, D. John Faulkner, Kim F. Albizati, Uma N. Sundram, Olivier Richou, Mohamad R. Agharahimi
Publikováno v: The Journal of Organic Chemistry. 56:378-387
Syntheses of both (-)-furodysinin ((-)-3a) and (-)-furodysin ((-)-2a) using analogous pathways have been accomplished from (+)-9-bromocamphor in four steps, establishing the absolute configurations in both the dysin and dysinin metabolite series. Thi

The stereochemical requirement in the fragmentation of 9-bromocamphor derivatives. A new class of chiral pool elements containing asymmetric quaternary carbon centers
Autor: Uma N. Sundram, Kim F. Albizati
Publikováno v: The Journal of Organic Chemistry. 56:2622-2624
The fragmentation of 9-bromobornan-2-ol derivatives is dependent on both the orientation and identity of the leaving group at the 2-position. This has led to a synthesis of compounds containing useful quaternary carbon centers in carbocyclic six-memb
