title: A stereocontrolled synthesis of delta-trans-tocotrienoloic acid.
abstract: [reaction: see text] A concise stereoselective total synthesis of a naturally occurring polymerase beta inhibitor, delta-trans-tocotrienoloic acid (2), is described. The key step in the synthesis is an acid-catalyzed cyclodehydration reaction. Additionally, this report corrects a previously reported structural assignment, defines the absolute stereochemistry of 2, and defines key structural requirements for polymerase beta inhibition.
