DOI: 10.1021/acs.orglett.2c02834
Abstract: Rugosiformisin A, a skeleton-rearranged abietane-type diterpenoid with a spiro[4.5]decane motif, was isolated from Isodon rugosiformis. Its structure was unambiguously established via NMR spectroscopic analysis and single-crystal X-ray diffraction. A bioinspired asymmetric synthesis of rugosiformisin A… read more here.
