Abstract:
Homodesmotic reactions were designed to study substituent effects on stability of oxiranes, oxirenes, and dioxiranes. Good or fair correlation between their homodesmotic stabilization energies and Taft's dual-substituent-parameters has been found. Oxiranes are stabilized by σ-donating and π-donating substituents but destabilized by σ-accepting and π-accepting substituents. The π-effects on oxiranes are comparable to σ-effects for π-acceptor substituents and are much stronger than σ-effects for π-donor substituents. Oxirenes are stabilized by σ-donating, π-donating, and π-accepting substituents

Abstract:
The effect on the stabilities of benzoannelated oxirenes (oxacyclopropenes) of variations in the C-C bond electron density (as measured by Löwdin bond order) was studied computationally. Benzo[b]oxirene (4ox), naphtho[2,3-b]oxirene (5ox), naphtho[1,2-b]oxirene (6ox), anthro[2,3-b]oxirene (7ox), and anthro[1,2-b]oxirene (8ox) were investigated using the DFT pBP/DN* method as implemented in the program Spartan. This method was chosen because with 4ox it gave results similar to those from the much slower QCISD(T)/6-31G*//MP2(full)/6-31G* and MP4SDTQ/6-31G*//MP2(full)/6-31G* methods. The calculate

Abstract:
The isomerization of oxirene (oxacyclopropene) (1) to ketene, dimethyloxirene (7) to dimethylketene via the oxo carbene ("ketocarbene"), and the retro-Diels–Alder extrusion of oxirene and dimethyloxirene from their formal adducts (9 and 24, respectively) with benzene were studied computationally. All species were optimized at the MP2(fc)/6–31G(df,p) level; the species involving 1 were also subjected to MP2(fc)/6–31G(df,p) frequency and single-point CCSD(T)/6–31G(df,p) calculations. At the CCSD(T)/6–31G(df,p)//MP2(fc)/6–31G(df,p) level 1 isomerized to ketene in one step with a barrier of 2.8 kJ

Abstract The photochemical decomposition of α-diazoketone 1 in toluene gives rise to the formation of the well known keto carbene-oxirene equilibrium from which not only the product of the Wolff rearrangem ent can be derived but also the com pounds 5, 6 and 7 which are formed directly via the corresponding keto carbenes A and B respectively.

Abstract:
Crossover experiments between isotopomeric species of 2-diazo-1-oxo-1-phenylethane (18O, 13C, D) establish beyond doubt that the oxygen migration accompanying the photochemical Wolff rearrangement is not the result of intermolecular processes. This is in agreement with a carbenecarbene rearrangement via an intermediate oxirene in competition to the rearrangement into a ketene, as reason for the partial oxygen migration in the Wolff rearrangement products.

Abstract:
We report the synthesis and solid-state 17O NMR characterization of three 17O-labeled oxiranes: (2S*,3S*)-2,3-bis(4-nitrophenyl)-[17O]oxirane, (2S*,3R*)-2,3-bis(4-nitrophenyl)-[17O]oxirane, and 2,2,3-triphenyl-[17O]oxirane. In addition, we have determined the crystal structure of (2S*,3R*)-2,3-bis(4-nitrophenyl)oxirane by X-ray crystallography. When the experimentally determined 17O NMR tensors for oxiranes (where the C–O–C bond angle is about 60°) are compared with those for dimethyl ether (where the C–O–C bond angle is 113°) and other R–O–R′ functional groups, we found that the highly constr

Optically enriched n-butyl 4,5- epoxypentanoate was prepared with a 64% enantiomeric excess via the porcine pancreatic lipase-catalysed hydrolysis of the racemic ester. The hydrolase-catalysed hydrolysis of two prochiral epoxydiesters; meso 2,3-epoxybutan-1 A-diyl dibutanoate and 2,3-epoxy-2-butanoyloxymethylpropan-1-yl butanoate, were performed with several lipases, with the enantiomerically enriched epoxymonoesters being obtained in up to 80% and 65% enantiomeric excesses, respecti
