-
Page/Page column 14, (2021/07/31)
The present invention relates to a method for the preparation of an N-monofluoroalkyl tropane, a method for the preparation of a trialkyltin tropane, a method for the preparation of an iodinated and/or radioiodinated tropane and the use of the N-monofluoroalkyl tropane as a precursor in the method for the preparation of the trialkyltin tropane and/or the iodinated and/or radioiodinated tropane.

New classes of de novo designed renin inhibitors are reported. Some of these compounds display excellent in vitro and in vivo activities toward human renin in a TGR model. The synthesis of these new types of mono- and bicyclic scaffolds are reported, and properties of selected compounds discussed.

Tropinone (6) was deprotonated with lithium diisopropylamide and with chiral lithium amides (18-24) and the resulting enolates (two enantiomers) were treated with electrophiles.The aldol reaction with benzaldehyde and deuteration were both diastereoselective.The former yielded only one isomer (exo, anti) of the aldol 8a; the latter proceeded from the exo face.This selectivity permitted us to probe the deprotonation of tropinone with lithium amides; it was concluded that the reaction involves predominantly the exo axial protons.The reaction of tropinone enolate with ethyl chloroformate led, via a ring opening, to the cycloheptenone derivative 9.The reaction with methyl cyanoformate yielded, in the presence of silver acetate and acetic acid, the β-ketoester 8b; however, in the absence of these additives, and especially when 12-crown-4 was added to the enolate, a ring opening leading to the pyrrolidine derivative 10 occured instead.Deprotonation of tropinone with chiral amides proceeded with modest enantioselectivity.A synthesis of non-racemic anhydroecgonine via this strategy allowed establishing the absolute stereochemistry of deprotonation.
