The first continuous flow process was developed to synthesize N-methyl secondary amines from alkyl mesylates and epoxides via a nucleophilic substitution using aqueous methylamine. A variety of N-methyl secondary amines were produced in good to excellent yields, including a number of bioactive compounds or their precursors. Up to 10.6 g (88% yield) of an N-methyl secondary amine was produced in 140 min process time. The amination procedure included an in-line workup, and the starting mesylate material was also produced in continuous flow from the corresponding alcohol. Finally, an in-line process combining the mesylate synthesis and nucleophilic substitution was developed.

One-pot preparation of Julia-Kocienski sulfides and sulfones from alcohols

, (2019/08/12)
A method for one-pot preparation of Julia-Kocienski sulfides and sulfones from alcohols and thiols is reported. A variety of primary alcohols were converted to the corresponding mesylates by methansulfonyl chloride and triethylamine in THF. After the reaction is complete, thiol (1 or 10) and either NaH or t-BuOK were added. The Julia-Kocienski sulfides 3, 9 and 11 were prepared by one-pot two steps procedure from alcohols in 76–96% yields (16 examples). Furthermore, after the sulfide formation, the reaction mixture was neutralized by p-toluenesulfonic acid and treated with H2O2 and ammonium molybdate in EtOH to give the Julia-Kocienski sulfones 4 in good yields except for trans-2-hexen-1-ol.
