Relevant academic research and scientific papers

Synthetic studies on (+)-hydantocidin (2): Aldol addition approaches toward the stereoisomers of (+)-hydantocidin

The spiro-hydantoin ring at the anomeric position of D-and L-furanose was constructed by using aldol addition followed by acid promoted cyclization and the synthesis of thestereoisomeis of (+)-hydantocidin, L- and D-series of spiro-furanose 2, 3, 4 and 5.

SYNTHETIC STUDIES ON (+)-HYDANTOCIDIN (4): SYNTHESIS OF STEREOSISOMERS OF (+)-HYDANTOCIDIN

The stereoisomers of (+)-hydantocidin were synthesized by diastereoselective dihydroxylation directly or epoxidation followed by ring opening of 1-oxa-6,8-diazaspirononane-3-ene-7,9-dione systems.
