    Abstract: THE PRESENT INVENTION RELATES TO DERIVATIVES OF DIBENZOCYCLOHEPTENES USEFUL BECAUSE OF THEIR ANTIDEPRESSANT ACTIVITY. THE INVENTION INCLUDES THESE COMPOUNDS AS WELL AS PROCESSES AND INTERMEDIATES USEFUL IN THEIR PREPARATION. THESE COMPOUNDS ARE PREPARED FROM THE KNOWN 3A,12B - DIHYDRO-2,2-DIMETHYL-5H-DIBENZO(O,4:6,7)CYCLOHEPTA(1,2-D) - 1,3-DIOXOL-8-ONE AND DERIVATIVES THEREOF WHICH CONTAIN ADDITIONAL SUBSTITUENTS IN ANY POSITION OF THE BENZENOID RING. THIS STARTING MATERIAL, ALTERNATVELY KNOWN AS THE ACETONIDE OF 10,11-DIHYDROXY10,11-DIHYDRO-5H-DIBENZO-(A,D)CYCLOHEPTEN-5-ONE IS CONVERTED BY TREATMENT WITH A 3 - DIALKYLAMINOPROPYLIDENE MAGNESIUM HALIDE TO PRODUCE THE CORRESPONDING 5-HYDROXY -5 - (3DIALKYLAMINOPROPYLIDENE) COMPOUND WHICH IS THEN DEHYDRATED UNDER ACIDIC CONDITIONS TO PRODUCE THE ACETONIDE OF 10,11-DIHYDROXY-10,11-DIHYDRO-5(3-DIALKYLAMINOPROPYLIDENE) - 5H-DIBENZO(A,D)CYCLOHEPTENE. THIS PRODUCT IS HYDROLYZED TO PRODUCE THE CORRESPONDING 10,11 - DIHYDROXY - 5-(3-ALKYLAMINOPROPYLIDENE)-5H-DIBENZO(A,D)CYCLOHEPTENE.

    Abstract: DIALKYL-SUBSTITUTED DERIVATIVES OF ACETALDEHYDE REACT EXOTHERMICALLY WITH GLYOXAL IN THE PRESENCE OF AN AQUEOUS BASE TO FORM BICYCLE FURODIOXOLE RING COMPOUNDS. FOR EXAMPLE, ISOBUTYRALDEHYDE AND GLYOXAL IN THE PRESENCE OF AQUEOUS SODIUM CARBONATE REACT TO FORM TETRAHYDRO-2ISOPROPYL-6,6-DIMETHYLFURO(2,3-D)-1,3-DIOXOL-5-OL. THE BICYCLIC FURODIOXOLES ARE VALUABLE INTERMEDIATES IN THE SYNTHESIS OF POLYOLS, WHICH ARE THEMSELVES USEFUL, FOR EXAMPLE, AS INTERMEDIATES IN THE PREPARATION OF ALKYL RESINS, PLASTICIZERS FOR POLYVINYL CHLORIDE COMPOSITIONS AND AS HUMECTANTS.
