1,1,3,3-Tetramethyldisiloxane (TMDS) has been developed as an excellent dual-purpose reductant for the highly regioselective ring cleavage of various hexopyranosyl 4,6-O-acetals with Cu(OTf)2 or AlCl3 to afford the corresponding primary and secondary ethers. Its application to the concise synthesis of carbohydrate-based surfactants is highlighted.
1,1,3,3-四甲基二硅氧烷 (TMDS) 已被开发为一种优异的双用途还原剂,用于各种吡喃己糖基 4,6-O-缩醛与 Cu(OTf)2 或 AlCl3 的高区域选择性环裂解,以提供相应的初级和次级醚。强调了其在碳水化合物基表面活性剂的简明合成中的应用。
