Reactivity of polyvinylogation: Easy and rapid access to different polyenals
This work describes the synthesis and the reactivity of three reagents of polyvinylogation 1-3. By condensation with several aldehydes and ketones, these reagents allow the introduction of three or four doubles bonds, leading to polyenals 5-6 in one or tw
FUNCTIONALIZED VINYLIC ORGANOLITHIUM COMPOUNDS, SYNTHETIC EQUIVALENT OF ω-LITHIO SORBALDEHYDE.
Functional vinylic anions 2 and 3 react with aldehydes and ketones leading after hydrolysis to polyenic aldehydes 7.They have been used for the synthesis of navenone B 8.
