An efficient and scalable synthesis of the clinical candidate 1 is described. The first-generation synthesis built the enantioenriched nitro-aminoindanol core from 6-nitroindanone using a five-step literature route. The second-generation route used a

Acylation of 1,3-disubstituted thioureas with methyl malonyl chloride followed by base-catalyzed cyclization leads to the preparation of 1,3-disubstituted-2-thiobarbituric acids in high yield.

A five step synthesis of thiotomoxetine ( 2 ) is described. Installation of the aryl ether was accomplished using a highly efficient S N Ar fragment coupling between amino alcohol ( 4 ) and a 1-halo-2-methylsulfinylbenzene (X = F or Cl) followed by a

In one operation, metalloenamines derived from R -phenylethylamine (PEA) and a β-tetralone were treated with an electrophile followed by acrylic anhydride. The unpurified lactams were reduced to give 10b-angular benzoquinolinones (BQs).

Sharpless asymmetric dihydroxylation (AD) of 6-hepten-2-one with AD-mix-α® followed by acidification gives (1S,SR)-5-methyl- 6,8-dioxabicyclo[3.2.1]octane in moderate ee. This methodology defines a two-pot enantioselective construction of the (−)
