Enantioselective straightforward access to benzo[b]thiophene analogs of Azatoxin
摘要:
Horner-Wadsworth Emmons olefination followed by asymmetric hydrogenation allowed the first synthetic access to the chiral thiotryptophan with good enantiomeric excess. Oxazolidinone formation followed by a Pictet-Spengler condensation provided the benzothiophenic analog of Azatoxin. (C) 2012 Elsevier Ltd. All rights reserved.
