introduction of the side chain and cleavage from resin with a Cu(I)-catalyzed Grignard reagent. Parallel synthesis of the vitamin D(3) analogues was accomplished by a split and pool methodology utilizing radio frequency encoded combinatorial chemistry, and a manual parallel synthesizer for side chain diversification and deprotection. Additionally, we demonstrated the synthesis of various A-rings in a similar
描述了在固体支持物上高效合成维生素 D(3) 系统。开发了两种用于固相合成维生素 D(3) 的合成策略。一种用于 11-羟基类似物,另一种用于大多数其他合成类似物。在后一种策略中,磺酸盐连接的 CD 环 58 最初固定在 PS-DES 树脂上,得到固体负载的 CD 环 63(方案 10)。类似地,通过将 CD 环 10 连接到氯磺酸树脂 64 上来制备固体负载的 CD 环 63。维生素 D(3) 系统是通过 A 环氧化膦的 Horner-Wadsworth-Emmons 反应合成的固体支持的 CD 环,然后同时引入侧链并用 Cu(I) 催化的格氏试剂从树脂上裂解。维生素 D(3) 类似物的并行合成是通过使用射频编码组合化学的拆分和池方法以及用于侧链多样化和脱保护的手动并行合成器来完成的。此外,我们展示了在类似的协议中合成各种 A 环,以有效地制备积木。

activities in murine keratinocytes at micromolar concentration. No biological advantage was observed in this keratinocyte assay for the doubly modified hybrid analogs 20a-c over the singly modified parent (+)-2b. Analog (+)-2b, but surprisingly not the corresponding analog 20b differing from (+)-2b only in the side chain, showed considerable activity in nongenomic opening of calcium channels in rat osteosarcoma

A new class of analogues of 1 alpha,25-dihydroxy vitamin D3 has been synthesised, in which the sidechain (C-23 to C-27) has been removed and where new hydroxylated sidechains have been attached to the C-18 methyl group. These analogues show antiproliferative activity in U937 and HaCaT cells comparable to that of 1 alpha,25-dihydroxy vitamin D3. Lack of calcemic activity makes these analogues potentially
