The Chemistry of 2H-3,1-Benzoxazine-2,4(1H)-dione (Isatoic Anhydride). 201. Synthesis and Wittig Reactions of Dimethyl (4-Oxo-1,4-dihydro-Quinolin-2-yl)methanephosphonates
An experimentally simple, mild and straightforward synthetic route towards diversely functionalized (E)-3-acylacrylic acids is described, with Horner–Wadsworth–Emmons (HWE) reaction as the key step. The substrate scope and limitations of the HWE reaction were investigated with a range of β-ketophosphonates. Glyoxylic acid monohydrate was demonstrated to be fully compatible with the HWE reaction conditions
β-hydroxyphosphonate analogues is described. The use of a nucleoside β-ketophosphonate as the key intermediate allowed both the (R) and (S) isomers of β-hydroxyphosphonate analogues in the pyrimidineseries to be accessed. Such derivatives may be considered as stable mimics of 5

The asymmetric epoxidation of α,β-unsaturated ketones has been achieved by using functional and readily accessible primary-secondarydiamines as the catalysts, giving the useful alkyl epoxy products with good yields and high enantioselectivities (up to 99% ee).
