Stereodivergent Synthesis of Chiral Allenesa
|
Under each product the percent yield, diastereomeric ratio (d.r.), and enantiomeric ratio (e.r.) are given. Yields are isolated yields (0.4 mmol scale).
The e.r. and d.r. were determined by HPLC analysis using chiral stationary phases. Ph, phenyl. See the Supporting Information for experimental details and stereochemical proofs.
