Diastereoselective Additions of Allenylstannanes to Aldehydes

The allenylstannane 4 undergoes highly syn selective additions to α-branched aldehydes 8b and 8c in the presence of BF3*OEt2.With the β-alkoxy aldehyde 21, Cram-Felkin addition results with BF3*OEt2 as the Lewis acid, whereas MgBr2 leads to chelation-cont

Amino Acids and Peptides; 70. Optically Active α-Amino Acids, N-Boc-Aminoaldehydes and α-Amino-β-hydroxy Acids from 2,3-Epoxy Alcohols

Trichloroacetimidic esters of 2,3-epoxy alcohols are transformed into oxazolines 5 and dihydrooxazines 6, respectively, depending on the structure of the educts and the catalyst.The five-membered ring compounds 5 are transformed into erythro-α-amino-β-hydroxy acids (60-70percent from epoxy alcohols) via axazolidinones 11, 12, and 13. α-Amino acids and α-substituted α-amino acids 10 as well as the corresponding aldehydes 9 are obtained from the dihydrooxazines 6 (50-60percent from epoxy alcohols).
