| titleOfInvention | Process for preparing dl-strigol |
| abstract | A process for preparing dl-strigol, a potent seed germination agent, which comprises preparing the 2-bromomethyl-substituted methyl ester of 2,6,6-trimethylcyclohex-1-en-3-one-1-carboxylic acid, alkylating and cyclizing the said compound with an excess of dimethyl sodiomalonate to obtain methyl 1,4-diketo-7,7dimethyl-2,3,5,6-tetrahydroindane-2-carboxylate and its enol, subjecting the said keto and enol forms of the compound, in admixture, to alkylation with methyl bromoacetate followed by acidic hydrolysis and spontaneous decarboxylation to obtain methyl 1,5-diketo-7,7-dimethyl-2,3,5,6-tetrahydroindane-2carboxylic acid, reducing the said carboxylic acid with a hydride reducing agent and recovering and separating the resulting 1 Alpha ,4 Alpha -dihydroxy-7,7-dimethyl-4,5,6,7-tetrahydroindane2 Alpha -acetic acid Alpha and Beta lactones, formylating each of the Alpha -lactone and Beta -lactone, alkylating the respective resulting hydroxy methylene lactones with bromobutenolide and recovering dl-strigol, dl-4''-epi-strigol, dl4-epi-strigol and dl-4,4''-diepi-strigol. New compounds useful as intermediates in the above process are also shown. |
