[(1R)-3-Benzoyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-onato-κ²O,O′]chlorido(η⁶-p-cymene)ruthenium(II)

Abstract

The asymmetric unit of the title compound, [RuCl(C10H14)(C17H19O2)], contains two diastereomers. In both, the RuII ion has a tetra­hedral coordination, formed by two O atoms of the camphor-derived ligand and the p-cymene and Cl ligands. In the crystal structure, weak inter­molecular C—H⋯Cl inter­actions link the mol­ecules into columns propagated along [010].

“…The versatility and importance of camphor as a chiral starting material in the synthesis of natural products is primarily due to the availability of methods for the introduction of functional groups (Jennings & Herschbach, 1965;Pastrán et al, 2011). We have developed a series of complexes based on camphor 1,3-diketonato ligands (Spannenberg et al, 2002;Harrad et al, 2010;Ait Ali et al, 2006), and their application in catalytic asymmetric reactions has been described (Gaudo et al, 2011). In this work, we present the structure of a new heterocyclic compound (1,10,10-trimethyl-5phenyl-3-oxa-4-aza-tricyclo[5.2.1.02,6]dec-4-en-2-ol)) which we have synthesized by hetercyclization from benzylcamphor with hydroxylamine.…”
