合成路线1
该中间体在本合成路线中的序号:(XLII)Alternatively, the chiral phenylpropyl chloride (XXX) can also be prepared as follows: Reduction of the cinnamic acid (XXXVI) with H2 over Pd/C in ethyl acetate gives the phenylpropionic acid (XXXVII), which is treated with oxalyl chloride to yield the acyl chloride (XXXVIII). Condensation of (XXXVIII) with (+)-pseudoephedrine (XXXIX) by means of NaOH in toluene/water affords the chiral amide (XL), which is enantioselectively alkylated with 2-iodopropane (XLI) by means of LDA in THF to provide the adduct (XLII). Reduction of the amide group of (XLII) with BH3/NH3 in THF gives the already reported primary alcohol (XXIX), which is finally treated with POCl3 in hot toluene to afford the phenylpropyl chloride intermediate (XXX).
