  Reactions of oxathio-substituted crotyllithium with alkyl halides and carbonyl compounds. An example of an ambident nucleophile

  摘要：

  The lithiated anion (2), obtained by treatment of 2-(1-propenyl)-1,3-oxathiane (1) with sec-BuLi, reacts with alkyl halides yielding substitution products predominantly at the alpha-terminus; on the contrary, carbonyl compounds afford addition products at the gamma-terminus. The gamma-adducts readily cyclize to spiro oxathianes.
