β¦ Synopsis
A versatile preparation of a-alkoxyphosphonium bromides leading to en01 ethers by Wittig coupling was exploited for the convergent synthesis of pheromones from the Douglas-fir tussock moth and the olive fly Dacus oleae as well as an oxaspirolactone and C-glycoside.

Dichlorodimethylsilane is reacted with two equivalents of ketone enolates to give dimethylsilyl bis-enol ethers in good yields. Lithium tetramethylpiperidide (Li?Mp) as well as triethylamine (TEA) are used in deprotonation of ketones. An intramolecular aldol type of coupling has been achieved in an
