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
Reprint of: Synthesis of a tricyclic core of rameswaralide
Trost, Barry M.,Nguyen, Hien M.,Koradin, Christopher
, p. 2033 - 2036 (2011)
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. 2010 Elsevier Ltd.

STRUCTURE OF ACETYL FLUOROSULFATE. ACYLATION OF CYCLOPROPYL-SUBSTITUTED ALKENES WITH ACETYL FLUOROSULFATE
Gavrishova, T. N.,Shastin, A. V.,Balenkova, E. S.
, p. 402 - 406 (2007/10/02)
By methods of IR and 1H, 13C, and 19F NMR spectroscopy it was shown that acetyl fluorosulfate formed in the reaction of acetyl fluoride with SO3 exists in the covalent form.The acylation of cyclopropane-substituted alkenes (vinyl- and isopropenyl-cyclopropanes, 1,1-dicyclopropylethylene, 1-methyl-1-vinyl- and 1-isopropenyl-1-methyl-cyclopropanes) with acetyl fluorosulfate goes without the rearrangement of the carbon skeleton, and it enables us to prepare functional derivatives of cyclopropane in preparative yields.
Chemistry and structure-activity relationships of C-17 unsaturated 18-cycloalkyl and cycloalkyl analogues of enisoprost. Identification of a promising new antiulcer prostaglandin
Collins,Gasiecki,Perkins,Gullikson,Bianchi,Kramer,Ng,Yonan,Swenton,Jones,Bauer
, 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
