An effective synthesis of scalemic 3,5,5-trisubstituted pyrrolin-4-ones
摘要:
A new two-step method employs the intramolecular cyclization of metalated imino esters for the construction of scalemic 3,5,5-trisubstituted pyrrolin-4-ones (4). The imino esters in turn derive from alpha-disubstituted amino acids, the latter readily available via a new protocol exploiting the enantioretentive alkylation of oxazolidinones.
