New C2-symmetrical 1,2-diphosphanes for the efficient rhodium-catalyzed asymmetric hydroboration of styrene derivatives
Demay, Steandphane,Volant, Florence,Knochel, Paul
, p. 1235 - 1238 (2007/10/03)
A double [2,3] sigmatropic rearrangement enables the fast synthesis of novel C2-symmetrical 1,2-diphosphanes in good yields. These phosphanes (for example, 1; c-Hex = cyclohexyl) are highly efficient ligands for the rhodium-catalyzed asymmetric hydroboration of a wide variety of styrenes (see scheme). cod = 1,5-cyclooctadiene; DME = 1,2-dimethoxyethane.
Hydroxyhalogenations of acyloxycyclohex-2-enes. Part 3. Iterative 1,2-hydroxyiodination of acetoxycyclohex-2-ene: Preparation of tetraacetyl conduritol D
Bange, Johannes,Haughan, Alan F.,Knight,Sweeney, Joseph
, p. 1039 - 1046 (2007/10/03)
Compound 22, the tetraacetyl derivative of conduritol D, has been synthesized by repeated hydroxyiodination reactions in nine steps from acetoxycyclohex-2-ene.
Diastereospecific Hydroxyiodination of 1-Acetoxycyclohex-2-ene via Intramolecular Delivery of Oxygen
Bange, Johannes,Haughan, Alan F.,Sweeney, J. B.
, p. 1405 - 1408 (2007/10/02)
The previously unreported reaction of N-iodosuccinimide with acetoxycyclohex-2-ene to give monoacetates of 3-iodocyclohexane-1,2-diols is diastereospecific.
