Enantioselective addition of diethylzinc to aldehydes catalysed by a β-amino disulfide derived fromL-proline
摘要:
A novel beta-amino disulfide 2 is prepared and is effective at catalytic levels (1.25-2.5 mol%) in the enantioselective addition of diethylzinc to aldehydes providing (R)-secondary alcohols in up to 99% ee.
Synthesis of chiral β-amino sulfides and β-amino thiols from α-amino acids
摘要:
Bifurcated routes to two series of chiral secondary beta-amino sulfides 5a - c and 11a - c have been developed from L-proIine and (S)-phenylglycine, respectively. The developed methodology has also led to the synthesis of the tertiary beta-amino thiol 7 and the primary beta-amino sulfide 1 2 from L-proline and (S)-phenylglycine, respectively.
