First total synthesis of (−)-(3S,6R)-3,6-dihydroxy-10-methylundecanoic acid
摘要:
The first total synthesis of (3S,6R)-3,6-dihydroxy- 10-methylundecanoic acid was accomplished from commercially available 1-bromo-3-methylbutane in 11 steps and 25.8% overall yield. The key steps were asymmetric allylic alkylations via allyldiisopinocampheylborane and hydroboration-oxidation. (c) 2005 Elsevier Ltd. All rights reserved.
A new synthesis of (-)-(3S,6R)-3,6-dihydroxy-10-methylundecanoic acid, a β-hydroxy carboxylic acid, has been accomplished using a cross-metathesis reaction between two terminal olefin intermediates as the key step.
