Different chiral spiroketal skeletons are obtained, in a versatile manner, by iterative alkylations of acetone N,N-dimethylhydrazone with iodides 2 followed by a one-pot deprotection/spirocyclization sequence. This methodology has been applied successfully to the synthesis of 1,7-dioxaspiro[5.5]undecane and 1,6-dioxaspiro[4.5]decane systems.
以通用的方式,通过将丙酮N,N-二甲基hydr与碘化物2进行迭代烷基化,然后进行一锅脱保护/螺环化顺序,可以获得不同的手性螺环骨架。该方法学已成功应用于1,7-二氧杂螺[5.5]十一烷和1,6-二氧杂螺[4.5]癸烷体系的合成。
