The enantioselective synthesis of the oxa-pinnaic acid framework has been achieved through internal asymmetric induction. The synthetic strategy pursued illustrates the adaptability of the Achmatowicz oxidative rearrangement for the synthesis of complex spirocyclic pyrans starting from tertiary alcohols.
通过内部不对称诱导已实现oxa-pinnaic酸框架的对映选择性合成。所采用的合成策略展示了Achmatowicz氧化重排在从三级醇合成复杂螺环吡喃方面的适应性。
