, p. 1403 - 1406 (1986)
Treatment of the diazocarbonyl compounds (2), readily prepared in 3 steps from methyl acetoacetate, with a catalytic amount of rhodium (II) acetate, leads to the formation of the cyclic ethers (3).
RHODIUM CARBENOID MEDIATED CYCLISATIONS. PART 2. SYNTHESIS OF CYCLIC ETHERS
Heslin, Julie C.,Moody, Christopher J.
, p. 1417 - 1424 (2007/10/02)
Alkylation of the dianion of methyl acetoacetate with the t-butyldimethylsilyl protected α,ω-halogeno alcohols (1)-(9) gives the β-keto esters (1) which are converted into the diazo alcohols (3) by diazo transfer and desilylation.Rhodium carbenoid cyclisa
