A method for the synthesis of dihydrobenzofurans by a direct aryl C−O bond formation is described. A mechanistic pathway for the reaction, distinct from previously described similar transformations, allows for mild reaction conditions that are expected to be compatible with functionalized substrates.

The first dynamic kinetic asymmetric amination of alcohols via borrowing hydrogen methodology is presented. Under the cooperative catalysis by an iridium complex and a chiral phosphoric acid, a-branched alcohols that exist as a mixture of four isomers undergo racemization by two orthogonal mechanisms and are converted to diastereo- and enantiopure amines bearing adjacent stereocenters. The preparation of diastereo- and enantiopure 1,2-amino alcohols is also realized using this catalytic system.

-tetrahydrocannabinol (desoxy-THC) derivatives, or an enantiomer, diastereomer, racemate, or pharmaceutically acceptable salt thereof, are useful for neuroprotection, treating pain, or treating a disease associated with alpha-1 glycine receptor (α1GlyR) and/or alpha-3 glycine receptor (α3GlyR) deficiency. Drug conjugates of the derivatives can be made.
