Abstract: A barley diterpene synthase (HvKSL4) was found to produce (14S)-cleistantha-8,12-diene (1). Formation of the nearly planar cyclohexa-1,4-diene configuration leaves the ring poised for aromatization, but necessitates a deceptively complicated series of rearrangements steered through a… read more here.

Abstract: This contribution describes the synthesis of an unsymmetrical substituted tetraalkoxy[2.2]paracylophane-1,9-diene comprised of an ortho-substituted and a para-substituted dioctyloxybenzene. (Sp)-4,5,12,15-tetraoctyloxy-[2.2]paracyclophane-1,9-diene ((Sp)-pCpd) and (Rp)-4,5,13,16-tetraoctyloxy-[2.2]paracyclophane-1,9-diene ((Rp)-pCpd) are formed as planar chiral enantiomers. Unlike other tetraalkoxy-substituted pCpds that form… read more here.

Abstract: The cis/trans stereochemistry of repeating alkenes in polymers provides a powerful handle to modulate the thermal and mechanical properties of these soft materials, but synthetic methods to precisely dictate this parameter remain scarce. We report… read more here.

DOI: 10.1039/d1qo00852h
Abstract: A family of 9-azabicyclo[3.3.1]nonadiene ligands were developed, and the nitrogen atom in the bridged ring enables a facile immobilization of diene ligands to silica. read more here.
