Syntheses of 5-chlorouracils/thymines with 1-[phosphono(methyl/ difluoromethyl)]-1,2-unsaturated-moiety-substituted methyl groups at N(1) and human thymidine phosphorylase inhibitory activity

By attaching (methyl)- or (difluoromethyl)-phosphonate groups to the 1-positions of ethene, cyclopentene or benzene, and attaching 1-(methyl)-5-chlorouracil or 1-(methyl)thymine groups to the corresponding 2-positions, compounds 1 - 5 were prepared as pot

Method for manufacturing 3-isochromanone

The present invention intends to provide a method for producing 3-isochromanones represented by formula (II) useful as a synthetic starting material of medicals or agricultural chemicals and the cyano compound represented by formula (I) by an industrially advantageous method in a high yield.Disclosed herein is a method for manufacturing a 3-isochromanone represented by the following formula (II): (wherein R2, R3, R4 and R5 each independently represents a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group),said method is characterized by comprising the steps of:hydrolyzing a cyano compound represented by formula (I): (wherein R1 represents a hydrogen atom, an alkyl group or an aryl group, and R2, R3, R4 and R5 have the same meanings as defined above) and subjecting the hydrolyzate to intra-molecular cyclization.

Imidazopyridine compounds and processes for preparation thereof
