## Abstract 1‐(2,4,6‐Trialkylphenyl)phospholes **__1a,b__** possess a moderate aromatic character. Despite of that they underwent a sigmatropic rearrangement at 150°C to afford 2H‐phospholes **__2a,b__** which by trapping with tolane, or in reaction with another unit of **__2__** gave [4 + 2] cyclo
1 and alkenes 2 with an electron-withdrawing or an electron-donating group 2 a-f and 2 g-h regioselectively yields the 4-substituted and the 3-substituted 2-hydroxy-1,2,3,4\_tetrahydropyridines 3 respectively. Dehydratisation of 3 with electron-withdrawing groups at C-4 gives the 1,4\_dihydropyridin
