Group 5 Metal Binaphtholate Complexes for Catalytic Asymmetric Hydroaminoalkylation and Hydroamination/Cyclization
Alexander L. Reznichenko,Thomas J. Emge,Stephan Audörsch,Stephan Audörsch,Eric G. Klauber,Kai C. Hultzsch,Bernd Schmidt +6 more
TL;DR: In this paper, 3,3′-Silylated binaphtholate tantalum and niobium complexes were shown to be efficient catalysts for asymmetric hydroaminoalkylation of N-methylaniline derivatives and N-benzylmethylamine with simple alkenes in enantioselectivities of up to 80% ee.

Stereoselective Total Synthesis of Atractylodemayne A, a Conjugated 2(E),8(Z),10(E)-Triene-4,6-diyne
Bernd Schmidt,Stephan Audörsch +1 more
TL;DR: The first total synthesis of the polyacetylene natural product atractylodemayne A is reported, achieved through a tethered ring-closing metathesis approach, comprising a Ru-catalyzed RCM followed by a base-induced elimination.

Stereoselective Synthesis of 2Z,4E-Configured Dienoates through Tethered Ring Closing Metathesis
TL;DR: A two-step sequence leading from racemic allylic alcohols and vinylacetic acid to ethyl (2Z,4E)-dienoates is described, which involves Steglich esterification of the reactants and a one-pot ring closing metathesis–base induced elimination–alkylation reaction to furnish the products in high stereoselectivity.

Stereoselective Total Syntheses of Polyacetylene Plant Metabolites via Ester-Tethered Ring Closing Metathesis.
Bernd Schmidt,Stephan Audörsch +1 more
TL;DR: The results presented herein do not only showcase the utility of this tethered RCM variant but have prompted the originally assigned absolute configurations of chiral polyacetylenes from Atractylodes macrocephala should be revised or at least reconsidered.
