Enantiogenic synthesis of (R)-(−)-3-hydroxy-1-penten-4-one
摘要:
Condensation of pyruvate and acrolein with whole cells of baker's yeast resulted in a mixture of 3-hydroxy-1-penten-4-one 1 and 4-hydroxy-1-penten-3-one 2. The absolute configuration (R) and the enantiomeric excess (ee 72%) of the compound 1 were determined. (C) 2003 Elsevier Science Ltd. All rights reserved.
