- SYNTHESIS OF PROTECTED α-KETOESTER DERIVATIVES USING SILYL KETENE ACETALS OF ALKYL DIALKOXYACETATES
-
Two readily accessible (RO)2, C=C(OSiMe3)(OR) react smoothly with oxygenated electrophiles (aldehydes, ketals, orthoesters) leading,, with good yields, to the corresponding β-functionalized α,α dialkoxyesters. Key words: 1,2,2 trialkoxy-1-trimethylsilylox

- LITHIOPENTAMETHOXYCYCLOPROPANE: PRECURSOR FOR THE SYNTHESIS OF HIGHLY OXYGENATED CYCLOPROPANES
-
Pentamethoxychlorocyclopropane (1) affords the corresponding lithiocyclopropane (2) upon treatment with t-butyllithium.Reagent 2 can be quenched with H2O, MeI, Me3SiCl, or MeSSMe to give excellent yields of highly oxygenated cyclopropanes 3-6.
