Asymmetric Synthesis of Ring Functionalized trans-2,6-Disubstituted Piperidines from N-Sulfinyl δ-Amino β-Keto Phosphonates. Total Synthesis of (−)-Myrtine
摘要:
Sulfinimine-derived N-sulfinyl delta-amino beta-ketophosphonates are transformed via the enaminones to the phosphoryl dihydropyridones that selectively give trans-2,6-disubstituted 1,2,5,6-tetrahydropyridines on organocuprate addition and dephosphorylation.
