Regeneration of 6-fluoro-4-chromanone from by-products in the synthesis of sorbinil
-
, (2008/06/13)
6-Fluoro-4-chromanone, a sorbinil intermediate, is regenerated from enantiomeric and mixtures of enantiomeric and racemic compounds obtained as major by-products in the synthesis of sorbinil. The regenerated intermediate is useful in the synthesis of additional sorbinil.
Pinane derivatives

, (2008/06/13)
Pinanes substituted by a group X in the 3-position which group is formyl, or its alkyl-acetals or alkyl-hemiacetals, carboxylic acid, carboxylic acid chloride, carboxylic acid amide, hydroxymethyl or aminomethyl substituted in a specific manner at the nitrogen, the optical isomers of these compounds and a process for their manufacture by hydroformylation of α-pinene in the presence of rhodium catalysts, and conversion of the 3-formylpinane first produced into the above derivatives by conventional methods.
Resolution of racemic pantolactone
-
, (2008/06/13)
A process for resolving racemic α-hydroxy-β,β-dimethyl-γ-butyrolactone, referred to as D,L-pantolactone, into its optical antipodes, based on the separation of diastereomeric salts of D,L-pantoic acid (α,γ-dihydroxy-β,β-dimethylbutyric acid), produced from D,L-pantolactone, by means of (-)-3-aminomethylpinane, (+)-3-aminomethylpinane or one of their acid addition salts, as a new resolving agent.
