No products arising from a nucleophilic reaction at C-2 were observed. The reaction with acetic acid also takes place regioselectively at C-3, but the initially formed anfz-3-acetoxy product undergoes an acyl migration to give the anti-3-hydroxy-2-acetamino product (see Scheme 21). [Pg.106]

In analogy to the /f-hydroxy-y-lactones, / -acetamino-y-lactones can also be a-alkylated by means of their dianions, which again are mostly prepared by the addition of 2 equivalents of LDA. [Pg.772]
