2-羟基1-甲氧基萘 | 1-methoxy-2-naphthol | 18515-10-1 | C11H10O2 | 174.199 |
1-Methoxy-2-naphthol was converted by MOM ether formation, lithiation at C-3, reaction with 3,3-dimethylacryloyl chloride, cyclization, and oxidation using cerium ammonium nitrate to 4-keto-α-lapachone (2,2-dimethyl-4-keto-1-oxa-1,2,3,4-tetrahydroanthra-5,10-quinone). Reduction by biotransformation using Mortierellaisabellina ATCC 42613 gave (S)-4-hydroxy-α-lapachone in high (> 95%) optical purity. Reduction of several 2,2-dimethyl-4-chromanones to the corresponding (S)-alcohols by M. isabellina is also reported. Keywords: biotransformation, chemoenzymatic, 4-hydroxy-α-lapachone, Mortierellaisabellina.
