 |  | 2-(TRIMETHYLSILYLOXY)FURAN Usage And Synthesis |  
 | Physical properties | bp 44–46 °C/17 mmHg; d 0.93 gmL?1. |  | Uses | 2-Trimethylsilyloxyfuran provides 5-substituted 2(5H)-furanones by alkylation, aldolization,
3 and conjugate addition; transforms quinones into furo-[3,2-b]benzofurans; useful for the four-carbon elongation of sugars. It is used in Synthetic Applications, Carbon–Heteroatom Bond Formation, Alkylation, Aldol-Type Reactions, Conjugate Addition, and Diels–Alder Reaction. |  | Uses | 2-(Trimethylsilyloxy)furan is a useful reagent for the preparation of natural and synthetic furanones with anticancer activity. |  | Preparation | Accessible by silylation of 2(5H)-furanone, which is obtained at very low cost by oxidation of furfural. |  | Purification Methods | Fractionally distil it using a short path column. 1H NMR in CCl4 has : 4.90 (dd, J 1.3Hz, 3H), 6.00 (t, J 3Hz, 4H) and 6.60 (m, 5H). [Yoshii et al. Heterocycles 4 1663 1976.] 4-Trimethylsilyloxy-3-penten-2-one (cis) (acetylacetone enol trimethylsilyl ether) [13257-81-3] M 172.3, b 66-68o/4mm, 61-63o/5mm, d 4 0.917, n D 1.452. Fractionally distil it and store it in glass ampoules which are sealed under N2. It hydrolyses readily in contact with moisture giving, as likely impurities, hexamethyldisiloxane and 2,4-pentanedione. [West J Am Chem Soc 80 3246 1958, Beilstein 4 IV 4003.] |
