  Resolution of albuterol acetonide

  摘要：

  The (R)-enantiomer of albuterol has been isolated via resolution of albuterol acetonide with (2S,3S)-di-O-benzoyl- or (2S,3S)-di-O-toluoyltartaric acid. The absolute configuration of the resolved acetonide was assessed by H-1 NMR analysis of its (R)-Mosher's ester, and confirmed by an X-ray crystal structure determination of the (R)-phenylethylurea derivative of the (S)-enantiomer.

  An atom economical and metal‐free, one‐pot two‐step asymmetric synthesis of highly valuable 2‐amino‐1‐arylethanols has been established from commercially available starting materials. The effectiveness and scalability of our approach have been demonstrated via the synthesis of the Salbutamol acetate salt, a bronchodilator widely used to treat asthma.

  Abstract Efficient enantioselective synthesis of (R)- and (S)-enantiomers of 2-(tert-butylamino)-1-(p-methoxyphenyl)-ethanol has been achieved in high enantiomeric excess by using asymmetric sulfoxide as a chiral auxiliary. The present synthetic approach was further extended to the asymmetric synthesis of (R)-salbutamol.

  An enantioselective synthesis of (R)-salbutamol has been carried out using the chiral, C2 symmetric acyl anion equivalent, (1R,3R)-1,3-dithiane 1,3-dioxide, which undergoes addition to an aromatic aldehyde with very high stereocontrol at 0 degrees C. Pummerer reaction and work-up with lithium ethanethiolate generated the alpha-hydroxy thiolester in high yield and further transformations led to the

  heteroatom-substituted alkenes is rarely explored and remains unprecedented, especially the earth-abundant metal catalyzed ones. Herein, the first cobalt-catalyzed asymmetric hydroboration of ketone-derived silyl enol ethers is reported, providing a convenient approach to access valuable enantiopure β-hydroxy boronic esters, which features broad substrate scope and excellent enantioselectivities.
