<p>Preparation of 2,3-dialkyl-4-phenyl-cyclohex-3 or 4-enes of general formula 3 or 4 R = lower hydroxyalkyl-, formyl-, carboxyl-, subst. carboxy(including alkali and alkaline earth metal salts). R1 = methyl-, dimethyl-, ethyl- R2 = methyl-, ethyl-, But combination R = carboxyl- R1 = methyl- R2 = ethyl- is excluded. Oral contraceptives for rats, mice, rabbits and dogs. This yields diamond shaped prisms of 2-methyl-3-ethyl-4-phenyl-cyclohexen-3-carboxyl-1.</p> |
