摘要

The aldehydes 4, 8a/8b and the acetals 5a/5b are prepared from the (S)-lactic acid derivative 3. Marschalk reaction with leucoquinizarine (10) affords rhodomycinones with one, two or three hydroxy groups in ring A. The 7, 9-cis-diol 21 (6-demethoxyfeudomycinone C) is the major cyclization product of the acetonides 20a/20b.
