Diastereoselective synthesis of oxazolo[3,4-b]tetrahydroisoquinolin-3-ones via Lewis acid TMSOTf-mediated Pictet–Spengler reaction
摘要:
An alternative and efficient method to stereoselectively synthesize oxazolo[3,4-b]tetrahydroisoquinolin-3-ones via a Pictet-Spengler reaction promoted by Lewis acid TMSOTf from readily available (S)-4-benzyl-2-oxazolidinone with various aromatic, aliphatic, and cyclic aldehydes under room temperature is described.
