A one-pot reaction of Boc-protected amino alcohols and 2-sulfobenzoic anhydride followed by the addition of a wide variety of primary amines has allowed rapid access to diverse libraries of amidosulfonates 1,2-C 6H4(SO3su
Direct copper-free domino conjugate addition-cycloallylation using organozinc reagents
Komanduri, Venukrishnan,Pedraza, Fernando,Krische, Michael J.

The Direct Approach: Enones possessing appendant allylic carbonates react directly with diorganozinc reagents in the presence of zinc diiodide [ZnI 2] to provide 5- and 6-membered ring products of tandem or domino conjugate addition-cycloallylation in good to excellent yield. In a related copper-free transformation, allylic carbonates are found to engage in direct allylic substitution with diorganozinc reagents.
Highly enantioselective copper-catalyzed allylic alkylation with phosphoramidite ligands
Van Zijl, Anthoni W.,Arnold, Leggy A.,Minnaard, Adriaan J.,Feringa, Ben L.
, p. 413 - 420 (2007/10/03)
New phosphoramidites were applied as chiral ligands in the Cu-catalyzed allylic alkylation with dialkylzinc reagents. A variety of substrates, reagents and chiral ligands were screened, resulting in improved catalytic methodology for allylic bromides in w
