Epoxidation of chiral camphor N-enoylpyrazolidinones with methyl(trifluoromethyl)dioxirane and urea hydrogen peroxide/acid anhydride: Reversal of stereoselectivity JOURNAL OF ORGANIC CHEMISTRY Fan, C. L., Lee, W. D., Teng, N. W., Sun, Y. C., Chen, K. M. 2003; 68 (25): 9816-9818
Abstract
Both diastereomeric isomers of epoxides with high optical purity are obtained when camphor N-methacryloylpyrazolidinone (1a) and N-tigloylpyrazolidinone (1b) are treated with a urea hydrogen peroxide/TFAA and methyl(trifluoromethyl)dioxirane, respectively.
