Acid-catalyzed synthesis of α,β-disubstituted conjugated enones by a Meyer-Schuster-type rearrangement in allenols
Alcaide, Benito,Almendros, Pedro,Cembellín, Sara,Martínez Del Campo, Teresa
, p. 1070 - 1078 (2015/03/30)
A novel, direct and simple methodology to gain access to α,β-disubstituted conjugated enones from α-allenols in a sustainable metal catalysis context, considering the inexpensiveness and environmentally friendliness of iron(III) species and protons, has b
Iridium-catalyzed asymmetric hydrogenation of α-substituted α,β-unsaturated acyclic ketones: Enantioselective total synthesis of (-)-mesembrine
Zhang, Qian-Qian,Xie, Jian-Hua,Yang, Xiao-Hui,Xie, Jian-Bo,Zhou, Qi-Lin
supporting information, p. 6158 - 6161 (2013/02/23)
A highly efficient asymmetric hydrogenation of α-substituted α,β-unsaturated acyclic ketones catalyzed by chiral spiro iridium complexes for the preparation of chiral 2-substituted allylic alcohols has been developed (ee up to 99.7%). This method provides a concise route to (-)-mesembrine (34% yield, 12 steps).
Singlet Photochemistry of Vinylcyclopropenes. Regioselectivity and Mechanism: Mechanistic and Exploratory Organic Photochemistry
Zimmerman, Howard E.,Wilson, David W.
, p. 692 - 697 (2007/10/02)
A study of the direct photochemistry of 1-anisyl-2-phenyl-3-methyl-3-isobutenylcyclopropene (5) was pursued with the objective of elucidating the reaction regioselectivity and casting light on alternative reaction mechanisms for this reaction known to aff
