| titleOfInvention | PROCESS FOR PRODUCTION OF (±)-3a,6,6,9a TETRAMETHYLDECAHYDRONAPHTHO[2,1-b]FURAN-2(1H)-ONE |
| abstract | The present invention relates to industrially useful production processes nin which (±)-3a,6,6,9a-tetramethyldecahydronaphtho[2,1-b]furan-2(1H)-ones and further (±)-3a,6,6,9a-tetramethyldo decahydronapbtho[2,1-b]furans are produced from raw materials which are readily available at low costs, through short steps and in a simple manner. The process for producing (±)-3a,6,6,9a-tetramethyldecahydronaphtho[2,1-b]furan-2(1H)-ones represented by the general formula (III):n nwhich includes the steps of cyclizing a homofarnesylic acid amide represented by the general formula (I):n nwherein R 1 and R 2 are each independently an alkyl group having 1 to 4 carbon atoms; and wavy lines each represents a carbon-to-carbon single bond having a cis or trans structure, nand/or a monocyclohomofarnesylic acid amide represented by the general formula (II):n nwherein R 1 and R 2 and wavy lines are the same as defined above; and dotted lines represent that a carbon-to-carbon double bond is present at any of positions represented by the dotted lines, nin the presence off an acid agent; and subjecting the cyclized product to hydrolysis. |
