One-pot method of preparing benzoyl the branch stands lactone (by machine translation)

The present invention discloses a one-pot method for preparing benzoyl the branch stands lactone. At the same in the reaction container, to the branch stands lactone diol as raw materials, adding solvent S1 And triphenyl methyl chloride to primary hydroxyl position of the alkylation reaction, to obtain [...] lactone solvent S [...] hydroxy derivatives1 The reaction system, benzoyl chloride to continue adding hydroxyl position of acylation reaction, and adding solvent S2 , Recrystallization, get the branch stands lactone glycol double-hydroxy derivative; adding solvent S3 And acid solution hydrolysis reaction of the primary hydroxyl group position, make the branch stands lactone crude benzoyl; adding solvent S4 Or/and S5 , Recrystallization, disposable and preparing the corresponding optically active benzoyl the branch stands lactone. The invention avoid each step reaction is repeatedly re-feeding the tedious; adequate reaction, little side reaction, high purity; after treatment is simple, high yield; and the operation is simple, time saving and high efficiency, saving the material, reducing the cost, and is suitable for industrial production.

Effect of allylic and homoallylic substituents on cross metathesis: syntheses of prostaglandins F2α and J2

We describe the effect of allylic (C15) and homoallylic (C11) substituents on cross metathesis reactions with Corey lactone derivatives. This strategy has led to the successful syntheses of PGF2α and PGJ2.
