A convergent synthesis of the [4.4]-spiroacetal-γ-lactones cephalosporolides E and F
摘要:
A short convergent synthesis of the fungal metabolites cephalosporolides E and F is reported. The key step makes use of a chelation-controlled Mukaiyama aldol reaction to access the key acyclic spiroacetal precursor with the required syn stereochemistry. (C) 2010 Elsevier Ltd. All rights reserved.
