The title compds. [I; R1-R3 = H, OR4; R4 = H, (HO)2P(O), alkenoyl, carboxyalkanoyl, (dialkylamino)ethyl, haloacyl, (un)substituted H2NCO; R5 = alkyl] were prepd. as neoplasm inhibitors. PhCH2COCl and PhOMe were refluxed in C2H4Cl2 contg. AlCl3 to give 4-MeOC6H4COCH2Ph. This was refluxed with NaOEt and EtI to give 4-MeOC6H4COCHEtPh. The latter underwent Grignard phenylation with 4-MeOC6H4Br in ...
