## 3-(Diphenylphosphinojalfylltftanium reagent qenerated easily from allyldiphenylphosphine condenses with aldehydes to give (Z)-1,3-alkadienes in a highly reqio-and stereoselective manner. In contrast, lithiated allyldiphenylphosphine oxide condenses with aldehydes to give (El-1,3-alkadienes dir
During our on-going program dealing with the asymmetric synthesis of biologically active compounds, we previously reported the efficient and enantiomerically selective synthesis of 3-substituted piperidines (2a), 3 and 3-substituted piperazines (2b) 4 by diastereoselective alkylation of chiral non-r
