Kinetic resolution of 4,5-dihydroxylated cyclopentenones
摘要:
An asymmetric synthesis of trans-4,5-dihydroxylated cyclopentenones has been developed. The method involves a lipase-mediated kinetic resolution. (C) 2003 Elsevier Ltd. All rights reserved.
A direct asymmetric synthesis of a trans-4,5-difunctionalised cyclopentenone derivative has been achieved in 55% yield and 80% ee by organocatalysed rearrangement of a pyranone in tert-butanol by DABCO with simultaneous enzymatic resolution. (C) 2009 Elsevier Ltd. All rights reserved.
