naturally occurring hypocholesterolemic and antioxidant agent d-γ-tocotrienol ((2R), 3′-trans, 7′-trans-tocotrienol) differs from the related tocopherols (Vitamin E) by possessing isoprenoid side-chain unsaturation. The presence of this unsaturation severely limits the chemistry available for tagging the substance. We were able to synthesize d-γ-tocotrienol-5-2H from the natural product by selective bromination
天然存在的降胆固醇和抗氧化剂 d-γ-生育三烯酚((2R)、3'-反式、7'-反式-生育三烯酚)与相关的生育酚(维生素 E)不同,它具有类异戊二烯侧链不饱和度。这种不饱和度的存在严重限制了可用于标记物质的化学物质。我们能够通过选择性溴化(CS2 中的 NSB)然后使用 Pd/C 催化的肼-d4 转移还原从天然产物合成 d-γ-生育三烯酚-5-2H。版权所有 © 1999 John Wiley & Sons, Ltd.
