The synthesis of 6-deoxyerythronolide B (1) has been completed using the β-ketoimide dipropionyl building block 2 in the synthesis of the C1C7 and C8C15 subunits. A convergent double stereodifferentiating Mukaiyama aldol coupling reaction, a biomimetic deoxygenation, and a high-yield macrocyclization were employed in an 18-step synthesis of this natural product.
在C 1 = C 7和C 8 = C 15亚基的合成中,已使用β-酮
