Botrylactone: new interest in an old moleculedreview of its absolute configuration and related compounds [PDF]
, 2010 The absolute configuration of botrylactone, a unique compound with an interesting polyketide lactone skeleton with two oxirane bridges previously isolated from Botrytis cinerea and described as a powerful antibiotic, has been reviewed on the basis of ...

Focus on chirality of HIV-1 non-nucleoside reverse transcriptase inhibitors [PDF]
, 2016 Chiral HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) are of great interest since one enantiomer is often more potent than the corresponding counterpart against the HIV-1 wild type (WT) and the HIV-1 drug resistant mutant strains.

Confirmation of the stereochemistry of spiroviolene
Beilstein Journal of Organic Chemistry, 2023 We confirm the previously revised stereochemistry of spiroviolene by X-ray crystallographically characterizing a hydrazone derivative of 9-oxospiroviolane, which is synthesized by hydroboration/oxidation of spiroviolene followed by oxidation of the resultant hydroxy group.
