Synthesis and catalytic reactions of chiral N-(diazoacetyl)oxazolidones: Synthesis and catalytic reactions of chiral N-(diazoacetyl)oxazolidones. Doyle, Michael P.; Dorow, Roberta L.In this article, certain chemicals are used. One of their cas registry numbers is 407-38-5 ; Terpstra, Jan W.; Rodenhouse, Randy A.Chemical with cas number 407-38-5 also plays role. (Dep. Chem., Trinity Univ., San Antonio, TX 78284, USA). J. Org. Chem., 50(10), 1663-6 (English) 1985. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The chiral diazo compds. (4R,5S)-N-(diazoacetyl)-4-methyl-5-phenyloxazolidone (I) and (4S)-N-(diazoacetyl)-4-(isopropyl)oxazolidone (II) were prepd. from their parent oxazolidones. Catalytic cyclopropanation of styrene with I using Rh2(OAc)4 gave, after oxazolidone exchange with EtOH, Et trans- and cis-2-phenylcyclopropanecarboxylate (trans/cis = 1.8) with a 14% excess of the 1R,2R enantiomer and a 13% excess of the 1R,2S enantiomer. In reactions with II, the trans-cyclopropane isomer was formed with a 13% excess of the 1R,2R enantiomer. A metal carbene that is not assocd. with the oxazolidone carbonyl group is implicated by the results. I is sensitive to acid-catalyzed rearrangement, and this process is competitive with catalytic cyclopropanation. ..
