The A/B ring synthon 13, previously converted into daunomycinone(6) by Keay and Rodrigo,6 has been prepared in seven steps and 38% overall yield using benzamide directed ortho metalation strategy. Significant steps are: the incorporation of a four-carbon Grignard unit (10) into 9, dibal reduction of 11, and intramolecular aldol condensation of the resulting product 12 to give the dihydronaphthalene
A / B环合成子13先前已由Keay和Rodrigo转化为daunomycinone(6)6,它是使用苯甲酰胺定向原位金属化策略分七个步骤制备的,总产率为38%。重要的步骤是:将四碳格利雅单元(10)结合到9中,二苯基还原11,以及将所得产物12分子内醇醛缩合,得到二氢萘13。
