Hydrochloric acid and hydrobromic acid react with α-mono- and α, α-disubstituted β-lactones under ring cleavage leading unequivocally to the corresponding α-mono- or α, α-disubstituted β-halogenopropionic acids. These products are interesting starting materials for the preparation of new compounds and can be reduced by zinc and formic acid to the corresponding propionic acids. The described synthesis
The present invention relates to polymeric derivatives, which can be conjugated to an amino-containing drug to improve its in vivo properties. The polymeric derivative can subsequently be released to yield the drug in its native form. Methods of preparing and using these polymeric derivatives and drug conjugates are described.

The invention relates to 1,5-benzothiazepine and 1,2,5-benzothiadiazepine derivatives of formula (I). These compounds are bile acid modulators having apical sodium-dependent bile acid transporter (ASBT) and/or liver bile acid transport (LBAT) inhibitory activity. The invention also relates to pharmaceutical compositions comprising these compounds and to the use of these compounds in the treatment of cardiovascular diseases, fatty acid metabolism and glucose utilization disorders, gastrointestinal diseases and liver diseases.
