Total Synthesis and Structural Assignment of (-)-Fusaequisin A. [PDF]
Chemistry, 2022 Abstract(−)‐Fusaequisin A is an irregularly assembled polyketide isolated from the ascomycete Fusarium equiseti. Fusaequisin A shares a carbon backbone with curvicollide C from the ascomycete Podospora curvicolla but its absolute configuration remained hitherto unsettled.

NMR Spectroscopic Studies on (exo, endo) C-2 Monosubstituted Norbornene Derivatives
Chinese Journal of Magnetic Resonance, 2021 The 1H NMR spectra of C-2 monosubstituted norbornene and its derivatives are usually difficult to assign due to the anisotropy effect of norbornene ring and being a mixture of exo- and endo- isomers. Based on the preparation of configurationally pure C-2

Assigning functions to nucleolar structures [PDF]
Chromosoma, 1991 Nucleoli provide the fascinating possibility of linking morphologically distinct structures such as those seen in the electron microscope with biochemical features of the formation and stepwise maturation of ribosomes. Localization of proteins by immunocytochemistry and of rRNA genes and their transcripts by in situ hybridization has greatly improved ...
