Masked Lithium Bishomoenolates: Useful Intermediates in Organic Synthesis
The lithiation of the chloro ketals 9 with lithium naphthalenide at -78 deg C led to the corresponding masked lithium bishomoenolates 4, which are stable species under these conditions and react with different electrophilic reagents (H2O, D2O, i-PrCOH, Ph

2-(3-Lithiopropyl)- and 2-(3-lithiopropyl)-2-methyl-1,3-dioxolane: New masked lithium bishomoenolates in the synthesis of bifunctionalized compounds
2-(3-Lithiopropyl)- and 2-(3-lithiopropyl)-2-methyl-1,3-dioxolane (2) are prepaned by lithiation of the corresponding chlorinated precursors with lithium naphthalenide at -78°C. The reaction of these masked bishomoenolates with different electrophiles yie
