TiCl4-Promoted Multicomponent Reaction: A New Entry to Functionalized α-Amino Acids
摘要:
TiCl4-promoted multicomponent reactions involving N-tosyl imino ester, cyclic enol ether, and silane reagents in a single one-pot operation provide functionalized alpha-amino acids with multiple stereogenic centers in good to excellent yields. Cis/trans selectivities with optically active substituted dihydrofurans have been investigated.
