Abstract: The present application includes a composition comprising a non-racemic mixture a compound of Formula (R)-I, or a salt and/or solvate thereof, and (S)-I, or a salt and/or solvate thereof: wherein (R)-I, or a salt and/or solvate thereof, is present in the composition in a greater amount by enantiomeric equivalents, relative to (S)-I, or a salt and/or solvate thereof. Also included are methods of using these compositions for treating, for example, a psychiatric disorder. The compounds of Formula (R)-I and (S)-I include the enantiomers of 3,4-methylenedioxymethamphetamine (MDMA) and N-methyl-1,3-benzodioxolylbutanamine (MBDB). Also included in the present application is a method for treating various diseases, disorders or conditions using a therapeutically effective amount of (R)-MDMA, or a pharmaceutically acceptable salt and/or solvate thereof.

Abstract: The present application includes an enantiomerically pure compound of Formula (R)-I or a salt and/or solvate thereof Also included are compositions of the enantiomerically pure compound of Formula (R)-I as well as methods of using the compound of Formula (R)-I or composition thereof for treating, for example, disease, disorder or condition that benefits from psychotherapy. The present application also includes a composition comprising a non-racemic mixture a compound of Formula (R)-I, or a salt and/or solvate thereof, and (S)-I, or a salt and/or solvate thereof: wherein (R)-I, or a salt and/or solvate thereof, is present in the composition in a greater amount by enantiomeric equivalents, relative to (S)-I, or a salt and/or solvate thereof and uses thereof. Further included are process preparing a compound of Formula (R)-I or (S)-I.

Abstract: The present application includes processes for preparing the (R)- or (S)-enantiomers of 3,4-methylenedioxymethamphetamine (MDMA) and the (R)- or (S)-enantiomers of N-methyl-1,3-benzodioxolylbutanamine (MBDB) starting with the alkyl esters of 3,4-dihydroxy-L-phenylalanine (L-DOPA) or alkyl esters of 3,4-dihydroxy-L-phenylalanine (D-DOPA), respectively. The present application also includes novel intermediate compounds useful in the preparation of the enantiomers of MDMA and MBDB.
