A concise stereoselective synthesis of proposed dehydroindolizidine-alkaloids of types 179 and 207E1 was accomplished via Michael-type conjugate addition. A comparison of natural 207E and synthesised compound 207E on GC–FTIR revealed the double bond of natural 207E is most likely at the 7,8-position.
