Diastereoselective additions to aldehyde groups in the side-chain of π-allyltricarbonyliron lactone complexes
摘要:
pi-Allyltricarbonyliron lactone complexes containing aldehyde groups adjacent to the allyl system undergo addition reactions with a variety of organoaluminium reagents in moderate to excellent diastereoselectivity.

[Rh(CO)(2)Cl](2) is an effective catalyst for the ringopening of vinyl epoxides with alcohols and aromatic amines under neutral conditions at room temperature. The reaction occurs with excellent diastereo- and regioselectivity (>20:1) giving the trans-1,2-amino alcohols or alkoxy alcohols for a wide range of substrates. The regio- and stereochemistry of these reactions is complementary to that typically
