Copper-catalyzed asymmetric conjugate additions are powerful reactions that allow the formation of single-enantiomer building blocks in a few steps. However, highly enantioselective conjugate addition to five-membered-ring substrates is more challenging a
Platinum-catalyzed cycloisomerization of 1,4-enynes via 1,2-alkenyl rearrangement

The cycloisomerization of 1,4-enyne 1 in the presence of platinum(II) catalyst afforded 1,2,3-trisubstituted 1H-indene 2 and 20 in good to excellent yields. The reaction proceeded through an unprecedented 1,2-alkenyl rearrangement that afforded a novel re

Diethers of general formula: where R, RI, RII, RIII, RIVand RV, same or different, are H or linear or branched alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl radicals with 1-18 carbon atoms, provided that R and RIare not both H or CH3 or are not CH3 and n-propyl; RVIand RVIIthe same or different, are linear or branched alkyl, cycloaliphatic, aryl, or arylalkyl radicals having 1-18 carbon atoms; one or more of R to RVIImay be bonded to form a cyclic structure. The diethers are particularly useful in the preparation of Ziegler-Natta catalysts.
