  Bis(trimethylsilyl)-tert-butylaldimines 3 react with aldehydes in the presence of zinc bromide at room temperature to give, after hydrolysis, the desired α-alkyl α,β-ethylenic aldehydes in good yield and with very high E stereoselectivity. The reaction was believed to proceed via the α-silyl β-siloxyimines 4.

  We present herein the first oxidation of enynyl boronates for the synthesis of γ-lactones, including spiro-, and fused-butanolides as well as butenolides that are prevalent in nature products and bioactive molecules. The asymmetric version of this oxidation was also achieved in the presence of chiral ketone and Oxone. This process successively involves the oxidation of C(sp)−B bond, the epoxidation

  我们在此提出了用于合成γ-内酯的烯基硼酸酯的第一次氧化，包括螺环和稠合丁内酯以及在天然产物和生物活性分子中普遍存在的丁烯内酯。这种氧化的不对称形式也在手性酮和 Oxone 的存在下实现。该过程依次涉及 C(sp)-B 键的氧化、C-C 双键的环氧化和内酯化。
