合成路线1
该中间体在本合成路线中的序号：(VI)Condensation of the chiral 2-chloro-3-(alpha-methylbenzyl)tetrahydro-2H-1,3,2-oxaazaphosphorine 2-oxide (I) with 2-chloroethylamine (II) afforded the 2-(chloroethylamino) derivative (III). The chiral auxiliary group of (III) was then removed by catalytic hydrogenation with H2 over -Pd/C yielding (R)-2-(2-chloroethylamino)tetrahydro-2H-1,3,2-oxaazaphosphorine 2-oxide (IV). Acylation of (IV) with bromoacetyl bromide (V) in the presence of triethylamine hydrobromide furnished bromoacetamide (VI). The amide carbonyl group of (VI) was finally reduced by treatment with NaBH4 and BF3·Et2O.
