Herein, facile and enantioselective approaches to synthesize the core phthalide tetrahydroisoquinoline scaffold of (−)-β-hydrastine via both a CF3COOH-catalyzed (86% ee) and KHMDS-catalyzed (78% ee) epoxidering-opening/transesterification cascade cyclization from chiral epoxide under very mild conditions are described. The key elements include a highly enantioselective epoxidation using the Shi ketone
The invention relates to the field of biochemistry, biophysical chemistry, molecular biology, structural biology and medicine. More in particular, the invention relates to cross-β structure conformation. Even more particular, the invention relates to compounds capable of binding to a compound with cross-β structure conformation, i.e. cross-β structure binding compounds and uses thereof.
