항암항생제 6-Deoxybisanhydrodaunomycinone의 합성
趙仁鎬,魯永釗,朴時浩,안구현,申洪植,韓秉九 全北大學校 基礎科學硏究所 1994 基礎科學 Vol.16 No.-
항암항생제 Danuorubicin(1b)의 aglycone인 daunomycinone의 전이물질 6-deoxybisanhydrodaunomycinone(20)의 전 합성이 이루어졌다. 만들어진 enone 화합물 4를 phthalide sulfone7과 반응시킨 뒤 oxidation과 methylation을 시켜서 anthraquinone 화합물 10을 얻었다. 화합물 10의 benzy기를 bromination 시켜서 얻은 monobromo 화합물 11을 bis(tetrabutylammoumum) dichromate로 고리화반응을 시켜서 hydrox-yanthraquinone 화합물 16을 얻은 뒤 OH기를 thiophenol로 치환시켰다. sulfide 화합물 17은 phoshate buffer 용액속에서 m-CPBA로써 산화시켜서 anthraquinonyl sulfone 화합물 18을 얻은뒤 methy vinyl ketone(19)과 결합시켜서 화합물 20을 얻었다. A brief route for total synthesis of 6-deoxybisanhydrodaunomycinone(20) was described, namely the precursor of the daunomycinone, the aglycone of the anticancer antibiotic daunorubicin (1b). The prepared enone 4 was condensed with phthalide sulfone 7 to afford anthraquinone 10 after oxidation and methylation. The benzylic group of 10 was brominated, and subsequent oxidation with bis(tetrabutylammonium) dichromate followed by cyclization give hydroxyanthraquinone 16, which was displaced with thiophenol. Oxidation of 17 with m-CPBA in phosphate buffer solution afforded anthraquinonyl sulfone 18 which was condensed with metyl mvynyl ketone (19) to furnish 20.
