at the C2 or C3 position (alcohols, esters, amine, ether, acetal) are cleaved with RCOCl/NaI (R = Me, tBu) in acetonitrile to give regioselectively trifunctionalized derivatives. In all cases the cleavage occurs mainly or exclusively at the C-O bond the most remote from the functional group.
摘要 在 C2 或 C3 位官能化的四氢呋喃(醇、酯、胺、醚、缩醛)在乙腈中用 RCOCl/NaI(R = Me,tBu)裂解,得到区域选择性三官能化衍生物。在所有情况下,裂解主要或仅发生在离官能团最远的 CO 键上。
