Abstract: One novel tri-substituted tetrahydropyran type 8,7'-neolignan and its enantiomer with higher enantiomeric excess were synthesized from all cis-tetra-substituted tetrahydrofuran with an iodomethyl group by a hydride or H2 ring-expansion reaction. The normal hydride reductions of… read more here.

DOI: 10.3390/ijms232214062
Abstract: Three pairs of novel enantiomeric 8-O-4′ type neolignans (1a/1b–3a/3b), together with seven known analogues (4–10), were isolated from the whole plants of Saussurea medusa. Their structures were elucidated by extensive spectroscopic data analysis and electric… read more here.
