Synthesis of chiral N-protected β-amino alcohols by the use of UNCAs
摘要:
A facile synthesis of a wide variety of N-protected beta-amino alcohol derivatives under mild conditions is described. N-urethane protected amino acid N-carboxyanhydrides (UNCAs) were used as starting material and reduced into the corresponding alcohols with the appropriate hydride, sodium borohydride. The reaction is simple, unexpensive, easily scaled up, and proceeds without observable racemization.
