Acetals reactions with organocopper compounds

Nucleophilic substitutions reactions with organocopper compounds or the more widely applied organocyanocuprates in the presence of Lewis acids have been reported on a./S-ethylenic acetals and allylic mesylates or acetates. Mangeney and co-workers have reported regio- and diastereoselective Sn2 or Sn2 reactions on chiral acetals of cyclic aldehydes promoted by PhCu and Furthermore, organocoppers react efficiently... [Pg.222]

The organocopper compounds react mainly with halides and they also react with aryl compounds, acetals, tosylates (R-0S02-C6H4CH3(-/7)) and tolyflates (R-OSO2CF3). The reactions with halides are first order to each of the concentrations and they are Sn2 reactions. The order of reactivity of alkyl halides regarding the alkyl group is as follows ... [Pg.500]
