A highly enantioselective NiH-catalyzed hydrocyclization of alkynones with unparalleled anti- and endocyclic selectivities is described. The choice of the precatalysts has significant influence in tuning the regio- and enantioselectivity. Using Ni(OTs)su

experimental part, p. 1925 - 1930 (2010/04/24)
Synthesis and facile rearrangement and cyclization reaction of new dipropargylic disulfides are described. A possible mechanism for these transformations involving an initial double [2,3]-sigmatropic rearrangement to the elusive diallenyl disulfides via a thiosulfoxide intermediates is suggested.
