METHODS FOR PREPARING LEVORPHANOL AND RELATED COMPOUNDS, AND COMPOSITIONS THEREOF
-
Paragraph 0177-0182, (2020/04/29)
A method for producing substantially pure levorphanol and related compounds, when compared to the conventional process, is provided. In particular, a method for producing substantially pure levorphanol tartrate dihydrate is described. Also described are compositions comprising levorphanol and related compounds, particularly compositions comprising levorphanol tartrate dihydrate, levomethorphan, and norlevorphanol in which the levomethorphan and norlevorphanol are present in the composition in reduced levels.
DEUTERATED MORPHINAN COMPOUNDS FOR USE IN TREATING AGITATION
-
Page/Page column 25, (2017/02/24)
This invention relates to methods of treating agitation comprising administering a morphinan compound or a pharmaceutically acceptable salt thereof. This invention also provides the use in methods of treating agitation and related disorders with such a morphinan compound in combination with quinidine, or pharmaceutically acceptable salt of either or both thereof.
Contra-thermodynamic Hydrogen Atom Abstraction in the Selective C-H Functionalization of Trialkylamine N-CH3 Groups

We report a simple one-pot protocol that affords functionalization of N-CH3 groups in N-methyl-N,N-dialkylamines with high selectivity over N-CH2R or N-CHR2 groups. The radical cation DABCO+?, prepared in situ by oxidation of DABCO with a triarylaminium salt, effects highly selective and contra-thermodynamic C-H abstraction from N-CH3 groups. The intermediates that result react in situ with organometallic nucleophiles in a single pot, affording novel and highly selective homologation of N-CH3 groups. Chemoselectivity, scalability, and recyclability of reagents are demonstrated, and a mechanistic proposal is corroborated by computational and experimental results. The utility of the transformation is demonstrated in the late-stage site-selective functionalization of natural products and pharmaceuticals, allowing rapid derivatization for investigation of structure-activity relationships.
