Synthesis of Axially Chiral 2,2′-Bisphosphobiarenes via a Nickel-Catalyzed Asymmetric Ullmann Coupling: General Access to Privileged Chiral Ligands without Optical Resolution
Zuo, Ziqing,Kim, Raphael S.,Watson, Donald A.
, p. 1328 - 1333 (2021/02/01)
We report an asymmetric homocoupling of ortho-(iodo)arylphosphine oxides and ortho-(iodo)arylphosphonates resulting in highly enantioenriched axially chiral bisphosphine oxides and bisphosphonates. These products are readily converted to enantioenriched b

Disclosed are methods, compounds, and compositions useful for increasing autophagy and promoting longevity. The methods, compounds, and compositions relate to urolithins and urolithin precursors and use thereof. Certain urolithins are represented by Formula I, while certain urolithin precursors are represented by Formula IV. The urolithin may be urolithin A, urolithin B, urolithin C, or urolithin D. The urolithin precursor may be ellagic acid or an ellagitannin. The methods include in vivo, ex vivo, and in vitro uses of the compounds and compositions.
The first synthesis of C-terminal biphenyl moiety of vancomycin
Rama Rao,Chakraborty,Joshi
, p. 4045 - 4048 (2007/10/02)
A successful Palladium catalysed intramolecular coupling of phenyl rings corresponding to amino acids (R)-4-hydroxyphenylglycine and (S)-3,5-dihydroxyphenylglycine of vancomycin is achieved.
