## Abstract Both enantiomers of __endo__‐brevicomin (+)‐ and (βˆ’)‐3a were synthesized from D‐erythronolactone (1) and 2,3‐__O__‐isopropylidene‐L‐erythrose (2), respectively. In the course of the synthesis also the 7‐vinyl analogues (+)‐ and (βˆ’)‐3b of __endo__‐brevicomin are available. The key step o
