Antifungal activity of 1′-homo-N-1,2,3-triazol-bicyclic carbonucleosides: A novel type of compound afforded by azide-enolate (3+2) cycloaddition

The first report of 1′-homo-N-1,2,3-triazol-bicyclic carbonucleosides (7a and 7b) is described herein. Azide-enolate (3+2) cycloaddition afforded the synthesis of this novel type of compound. Antifungal activity was evaluated in vitro against four filamentous fungi (Aspergillus fumigatus, Trichosporon cutaneum, Rhizopus oryzae and Mucor hiemalis) as well as nine species of Candida spp. as yeast specimens. These pre-clinical studies suggest that compounds 7a and 7b are promising candidates for complementary biological studies due to their good activity against Candida spp.

Prostanoids: Synthesis of enantiomers of 15-deoxy-16-hydroxy-16-methylprostaglandin E1

Four optically pure isomers of methyl 11,16-dihydroxy-16-methyl-9-oxoprost-13-enoate (1a-1d) were synthesized using an approach reverse to the classical Corey procedure, the key intermediates being the easily accessible (-)- and (+)-enantiomers of the Corey lactone, 2a and 2b.
