A procedure for the solid phase synthesis of 1,2-diols and γ-lactones from α-(hydroxy)crotylstannane has been developed through transmetalation with InBr3. A variety of 1,2-diols and γ-lactones were synthesized in satisfactory yields and, in some cases, with excellent diastereoselectivity. The products are formed free of tin contamination.
通过 InBr3 的金属转移,开发了从 α-(羟基)巴豆基锡烷固相合成 1,2-二醇和 γ-内酯的方法。各种1,2-二醇和γ-内酯的合成都具有令人满意的产率,并且在某些情况下具有优异的非对映选择性。产品不含锡污染。
