DOI: 10.1021/acs.orglett.1c04261
Abstract: A stereoselective synthesis of the proposed and actual structures of the natural products preussochromones E and F is reported. The key step is a ring-closing metathesis to close the five-membered ring and install the trans… read more here.

DOI: 10.1039/d1cc01971f
Abstract: In this report, we revise the structure for a previously reported synthetic product proposed to be the 1R,2S-cannabidiol epoxide and reassign it as cannabielsoin using anisotropic NMR and synthetic chemistry methods. These results provide a… read more here.
