Selectivity in nickel-catalyzed rearrangements of cyclopropylen-ynes
Zuo, Gang,Louie, Janis
, p. 5798 - 5799 (2005)
The Ni/NHC-catalyzed rearrangement of cyclopropylen-ynes is described. Two different heterocycles, cyclopentane- or cycloheptene-based, were obtained. However, by employing ItBu as the NHC ligand, cyclopentane products were obtained selectively under mild
Synthesis of a tricyclic core of rameswaralide
Trost, Barry M.,Nguyen, Hien M.,Koradin, Christopher
supporting information; experimental part, p. 6232 - 6235 (2011/01/12)
A tricyclic core containing a 5,7-fused bicyclic unit of rameswaralide was prepared starting from a 1,6-enyne. The synthetic sequence involved (i) ruthenium-catalyzed [5+2]-cycloaddition of 1,6-enyne, (ii) an acyl radical based approach to construct the lactone, and (iii) a regioselective installation of the conjugated double bond by a concomitant sulfenylation-dehydrosulfenylation sequence.
Chemistry and structure-activity relationships of C-17 unsaturated 18-cycloalkyl and cycloalkyl analogues of enisoprost. Identification of a promising new antiulcer prostaglandin

, p. 2784 - 2793 (2007/10/02)
A series of Δ17 unsaturated cycloalkyl and cycloalkenyl analogues of enisoprost was synthetized to investigate the effects of ω chain unsaturation on gastric antisecretory activity and diarrheogenic side effects. Of these, the 17E, 18-cyclopent
