Title:
7-置換3-アルキル-3H-イソベンゾフラン-1-オン誘導体の製造方法
Document Type and Number:
Japanese Patent JP4571374
Kind Code:
B2
Abstract:
The present invention relates to a first compound having the formula wherein R is halogen, R1S(O)n or (R1)2NC(X)O; R1 is C1-C8alkyl, C1-C8haloalkyl, aryl-C1-C8-alkyl or aryl; n is 0, 1, 2 or 3; X is O or S; and R3 is C2-C5alkyl or C1-C5haloalkyl, or a salt thereof. The present invention is also directed to a second compound having the formula wherein R is fluorine, bromine, iodine, R1S(O)n or (R1)2NC(X)O; R1 is C1-C8alkyl, C1-C8- haloalkyl, aryl-C1-C8alkyl or aryl; n is 0, 1, 2 or 3; X is O or S; and R2 is hydrogen, C1-C4alkyl or C1-C4haloalkyl, with the proviso that R1 is different from C1-C8 alkyl or aryl if X is S, R is different from iodine if R2 is methyl, and R is different from fluorine, bromine or iodine if R2 is hydrogen.
