Four stereoisomers of nodulisporacid A (1) were synthesized by the concise approach which includes three-component reaction and subsequent one-pot construction of the whole framework. The (1)H NMR comparison of the derivatives (10-12) revealed the absolute configuration of natural 1 to be 4R,4'R,6'R. (C) 2010 Elsevier Ltd. All rights reserved.
