Thiones as superdipolarophiles. Rates and equilibria of nitrone cycloadditions to thioketones

1,3-Dipolar cycloadditions of N-methyl-C,C-diphenylnitrone (15) and N-methyl-C-phenylnitrone (16) with aliphatic thioketones are equilibrium reactions. The 1,4,2-oxathiazolidines were characterized and their dissociation constants measured by 1

Reaction of Oximes with Dimethyl Carbonate: A New Entry to 3-Methyl-4,5-disubstituted-4-oxazolin-2-ones

The reaction of ketone oximes with dimethyl carbonate (DMC) carried out in an autoclave at 180-190 deg C and in the presence of K2CO3 yields 3-methyl-4,5-disubstituted-4-oxazolin-2-ones.The reaction can be applied to both aliphatic and aromatic ketone oximes, provided that a methylene group be present near the C=N bond.Nonoptimized yields range from 22 to 48percent.The reaction seems to be a sigmatropic rearrangement where DMC plays a key role in causing the initial N-methylation of the oximes.

A CONVENIENT SYNTHESIS OF NITRONES BY N-ALKYLATION OF O-TRIMETHYLSILYLOXIMES

Aldoxime and ketoxime-O-trimethylsilyl ethers can be alkylated with trialkyl-oxonium tetrafluoroborates and alkyl triflates at or below room temperature to produce nitrones in good yields.
