  Total synthesis of (±)-5-iminodaunomycinone and (±)-4-demethoxy-5-iminodaunomycinone

  摘要：

  The total synthesis of (+/-)-5-iminodaunomycinone (4a) and (+/-)-4-demethoxy-5-iminodaunomycinone (4b) has been achieved from the readily available 5-methoxy-1,4-dihydroxy-9,10-anthraquinone (5a) and 1,4-dihydroxy-9,10-anthraquinone (5b), respectively. A short and convenient synthesis of (+/-)-daunomycinone (4c) has also been achieved by acid hydrolysis of 4a.

  The development of a general strategy for the construction of anthracyclinones based on a Diels-Alder reaction of substituted derivatives of 10-amino-9-hydroxy-1,4-anthraquinone is described. The key stages are (i) formation of N,O,O-triacyl derivatives of 1,4-dihydroxy-9,10-anthraquinone monoimines in a tautomer specific fashion, (ii) transacylation into N,N,O-triacyl derivatives of the corresponding 10-amino-9-hydroxy-1,4-anthraquinone, and (iii) Diels-Alder reaction with an appropriately substituted 1,3-diene regiocontrolled by steric factors. This strategy has been applied to the total synthesis of (+/-)-5-iminodaunomycinone (4) and (+/-)-4-demethoxy-5-iminodaunomycinone (3) and to a novel and short synthesis of (+/-)-daunomycinone (5).
