Studies in tetrahydrofuran synthesis. Complete β-lactone formation in the bromolactonization of A 2,4-disubstituted β, γ-unsaturated carboxylic acid
摘要:
A dienolate aldol/bromolactonization sequence has been used to demonstrate a new stereocontrolled route to protected alpha-(1-hydroxyalkyl) 2-oxetanones, and thus specifically functionalized tetrahydrofurans.
