Highly Enantioselective Organocatalysis with Bidentate Halogen Bond Donors

Angewandte Chemie International Edition, EarlyView.
In a model Mukaiyama aldol reaction with unbiased substrates, high enantioselectivity was achieved with a modifiable bidentate iodine(I)‐based halogen bonding organocatalyst. The crucial role of halogen bonding was confirmed by the low performance of the corresponding hydrogen bond donor and via DFT calculations.

Expanding the Inositol Pyrophosphate Toolbox: Stereoselective Synthesis and Application of PP‐InsP4 Isomers in Plant Signaling

Angewandte Chemie International Edition, Accepted Article.
Inositol pyrophosphates (PP‐InsPs) are highly phosphorylated signaling molecules that regulate diverse cellular processes, including phosphate homeostasis and energy metabolism across species. Despite extensive research on well‐characterized exhaustively phosphorylated PP‐InsPs, such as 5‐PP‐InsP5 (5‐InsP7) and 1,5‐(PP)2‐InsP4 (1,5‐InsP8), the ...
