Pyrido[1,2-a]pyrimidone analogs as PI3K inhibitors

The present invention discloses a class of pyrido[1,2-a]pyrimidone analogs as PI3K inhibitors, and particularly relates to a compound represented by a formula (I) or a pharmaceutically acceptable salt thereof. The formula (I) is defined in the specification.

α-Amino-α-vinyl-γ-butyrolactone derivatives from α-{[(trimethylsilyl)-methyl]alkylidene}-γ-butyrolactones

N-Protected α-amino-α-vinyl-γ-butyrolactones 1 are obtained by the aza-Michael-type addition of NsONHCO2Et to novel silylated α-ylidene-γ-butyrolactones 2, through ring opening of the intermediate aziridine and loss of the trimethylsilyl group.

Diastereoselective hydrogenations of α-alkyl α-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)methylene carbonyl compounds. New route to stereopure α-alkyl α-oxymethyl carbonyl compounds

Wittig condensation of the stabilised phosphoranes 9, 10 and 26 with 1-formyl-2,3,4,6-tetra-O-acetyl-β-D-glucopyranose 11 leads to the vinylogous carbonates 12, 13 and 22. The salts 27-30 and 44, prepared from the corresponding carbonyl compounds, ethyl f
