A short stereoselective synthesis of (+)-(6R,2′S)-cryptocaryalactone via ring-closing metathesis
Beilstein Journal of Organic Chemistry, 2009 A short stereoselective synthesis of (+)-(6R,2′S)-cryptocaryalactone was successfully completed. Key steps included the application of Carreira’s asymmetric alkynylation reaction to form a propargylic alcohol and subsequently lactone formation using the ...

Synthesis of cyclic proline-containing peptides via ring-closing metathesis
, 2003 Several dienes embedded in di- and tripeptides which incorporate proline have been prepared and subjected to ring-closing metathesis. Bicyclic peptides of well-defined amide geometry and of varying ring sizes were prepared.

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy
Angewandte Chemie International Edition, EarlyView.Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Molybdenum‐carbothioamide complexes as potential single‐source precursors for MoS2 thin film
Bulletin of the Korean Chemical Society, EarlyView.Novel molybdenum complexes were synthesized to apply for deposition of Mo‐containing thin films. All complexes were characterized, and they are likely to be used as single‐source precursors for MoS2 thin films. Abstract Molybdenum disulfide (MoS2) thin films are widely used in batteries, transistors, supercapacitors, and 2D materials owing to their ...

Phosphanyl Radicals From Bismuth‐Mediated Reactions and Sterically Encumbered Diphosphanes
Chemistry – A European Journal, EarlyView.Reactions of LiPR2 with BiCl3 selectively give diphosphanes R2P–PR2 in high yields, presumably via Bi─P homolysis. This includes challenging cases with bulky substituents R. Sterically encumbered diphosphanes release persistent phosphanyl radicals [PR2]• in thermally initiated equilibrium reactions.
