First syntheses of 1,13- and 1,15-dihydroxyherbertenes, and herbertenolide by applying intramolecular Heck reaction for the construction of adjacent quaternary centers
摘要:
1,13- and 1,15-Dihydroxyherbertenes and hebertenolide, typical herbertane-type sesquiterpenes with an oxidized methyl group, were synthesized by using intramolecular Heck reaction for the construction of adjacent quaternary centers. (C) 2001 Elsevier Science Ltd. All rights reserved.
Dynamic Chirality of (E)-5-Cyclononen-1-one and its Enolate
摘要:
It has been found that (E)-5-cyclononen-1-one (2a) exhibits marginal planar chirality owing to an insufficient topological constraint, whereas the enolates 3 derived from 2a show robust planar chirality. Enantioenriched enolates are easily prepared by enzymatic hydrolysis, and they show an ability to serve as chiral nucleophiles.
