摘 要:以L(fǎng)-苯丙氨酸(3)為原料,經(jīng)Boc保護、酰氯化、取代、脫羧、氯代,“一鍋”制得(S)-4-苯基-3-(叔丁氧羰基)氨基-1-氯-2-丁酮(6),優(yōu)化條件下收率達70.4%。6 經(jīng)還原和環(huán)合得到(2R,3S)-4-苯基-1,2-環(huán)氧-3-叔丁氧羰基氨基丁烷(1)。對影響收率的堿的種類(lèi)、反應溫度、還原劑等因素進(jìn)行了工藝優(yōu)化,優(yōu)化條件下收率85.7%,產(chǎn)品純度99%。1 及中間體的結構經(jīng)1H NMR、13C NMR和ESI-MS確證。該工藝方法操作簡(jiǎn)單,原料價(jià)廉、收率高。 |
關(guān)鍵詞:硫酸阿扎那韋;中間體;還原;環(huán)合 |

Abstract:L-Phenyl-alamine was Boc-protected to afford N-Boc-L-phenyl-alamine after using an one-pot method including acylating chlorination, substitution, decarboxylation and chlorination. (S)-4-Phenyl-3-(N-Boc-amino)-1-chloro-2-butanone (6) was obtained with a yield of 70.4%. Then (2R,3S)-4-phenyl-3-(N-Boc-amino)-1-oxirane-butane(1) was synthesized from compound 6 through reduction and cyclization with a yield of of 85.7% and a chromatographic purity of 99%. The affecting factors including the reaction temperature, the kinds of the base and the reductant were studied. The structures of the compound 1 and intermediates were characterized by 1H NMR, 13C NMR and ESI-MS. The preparation process was simple in operation, low in raw material cost, high yield. |
Key words:atazanavir sulfate; intermediate; reduction; cyclization |
