Polyvinylogation reagents : 1-lithio-4-trimethylsiloxy-penta-1,3-diene and 1-lithio-4-ethoxy-2-methyl-buta-1,3-diene
摘要:
Title products, lithiodienol ethers 6a and 7a, synthetic equivalents of 4-lithio pent-3-ene-2-one and 4-lithio-senecialdehyde were obtained by bromine-lithium exchange. They are choice reagents for the transformations l --> 2 and l --> 3, respectively.
