PRODUCTION OF OPTICALLY ACTIVE PHOSPHOLANES

The invention relates to phospholanes and diphospholanes of general formula (I), whereby R represents H, C1-C6-alkyl, aryl, alkyl aryl, SiR2 3, R2 represents alkyl or aryl, A represents H, C1-C6-alkyl, aryl, Cl, or (a), and B represents a binding link with 1-5 C-atoms between both P-atoms. The inven...

Beschreibung
Zusammenfassung:	The invention relates to phospholanes and diphospholanes of general formula (I), whereby R represents H, C1-C6-alkyl, aryl, alkyl aryl, SiR2 3, R2 represents alkyl or aryl, A represents H, C1-C6-alkyl, aryl, Cl, or (a), and B represents a binding link with 1-5 C-atoms between both P-atoms. The invention also relates to the use of said phospholanes and diphospholanes as a catalyst in asymmetric synthesis.
