Deprotonation of oxazolinyloxiranes: Formation of substituted acyloxiranes

Deprotonation of oxazolinyloxiranes 1a, 1h, and 1k with sBuLi/TMEDA at - 100 °C in Et2O furnishes oxazolinyloxiranyllithium compounds 1b, 1i, and 1I which are stable at low temperature and can be trapped with electrophiles to give substituted oxiranes 1c-1g and 1j. The reaction of 1b with aldehydes produced diastereomers syn (2a-d) and anti (3a-d). Oxiranyllithium 1i from trans-1-(4,4-dimethyl-2-oxazolinyl)-2-p-tolylepoxy-ethane (1h) was found to be configurationally stable while oxiranyllithium 1l, generated from the cis isomer 1k, was not. Oxazolinylepoxides 1d, 1j, and 1m could be deblocked to acyloxiranes 5a-e through oxazolidines 4a-e.

Pentavalent Organobismuth Reagents. Part 3. Phenylation of Enols and of Enolate and other Anions

The phenylation of enols and of enolate anions of ketones, β-diketones and keto esters has been studied using a range of Bi reagents.Under basic conditions C-phenylation is observed and, even hindered, perphenylated compounds are easily synthesized.Under neutral and acidic conditions ordinary ketones do not react and enolic systems give O-phenylation.A number of other anions have been phenylated under basic conditions, including the key compound indole wich mainly gave 3-C-phenylation.All these reactions can be supposed to have one of two alternative mechanisms, which parallel the two mechanisms proposed for the phenylation of phenols.
