Highly enantioselective routes to darzens and acetate aldol products from achiral aldehydes and t-butyl bromoacetate (cas 18991-98-5)

Add time:07/18/2019    Source:sciencedirect.com

New methodology is described for the enantioselective coupling of t-butyl bromoacetate with aldehydes to give anti-α-bromo β-hydroxy esters (1), useful precursors of chiral glycidic esters (2), acetate aldols (3), β-amino acid esters (4) and α-amino acid esters (5).
