A convenient one-pot synthesis of 1,2-azaphospholanium salts

HETEROATOM CHEMISTRY, Issue 7 2003
Inga M. Aladzheva
A novel facile one-pot synthesis of the 1,2-azaphospholanes by intramolecular alkylation of 3-halopropyl amides of tricoordinate phosphorus has been suggested. Using this method, a series of the differently N-substituted 1,2-azaphospholanium salts were synthesized. 3-Aminopropylphosphine oxides were obtained by hydrolysis of the salts. A probable mechanism of the 1,2-azaphospholanium salts formation is discussed. © 2003 Wiley Periodicals, Inc.

A New Stereoselective Synthesis of Cyclopropanes Containing Quaternary Stereocentres via Organocatalytic Michael Addition to Vinyl Selenones

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 11-12 2009
Francesca Marini
Abstract A novel organocatalytic method for the stereoselective synthesis of highly substituted cyclopropanes is reported. The Michael adducts, generated through the addition of ,-substituted cyanoacetates to easily accessible vinyl selenones catalyzed by a bifunctional ureidic catalyst, smoothly cyclize by intramolecular alkylation induced by a de-ethoxycarbonylation process. The one-pot sequence generates cyclopropanes bearing adjacent tertiary and quaternary stereocentres as single Z -isomers in moderate to high yields and good enantiomeric excesses. [source]
