Abstract
A total synthesis of (±) negamycine 1 has been achieved in 14 steps from the acrolein dimer 6, which possesses the same carbon skeleton as the key intermediate lactone 4. Treatment of 2-acetoxymethyl 3, 4-dihydro [2H] pyran 8, obtained from 6, with lead tetracetate gave the allylic hemiketal 15, which was converted into the corresponding anomeric methyl ethers 23. Hydroxylation of the double bond of 23 with mercuric acetate, occurred selectively at the γ- ...
