Abstract

This application is directed to compounds of the formula wherein j is 1; k is 0 or 1; m is 1, 2 or 3; n is 1 or 2; W1 and W2 are independently —O— or —S(═O)t—, where t is 0, 1, or 2; Y is ═C(R1a)—, where R1a is a member selected from the group consisting of H; F; Cl; CN; NO2; —(C1-C4) alkyl; —(C2-C4) alkynyl; fluorinated-(C1-C3) alkyl; fluorinated-(C1-C3) alkoxy; —OR16; and —C(═O)NR22aR22b; R22a and R22b are defined as set forth in the specification; —RA and RB are each a member independently selected from the group consisting of H; F; CF3; —(C1-C4) alkyl; —(C3-C7) cycloalkyl; phenyl; and benzyl; wherein said cycloalkyl, phenyl, and benzyl moieties are each independently substituted with 0 to 3 substituents R10, which is defined as set forth in the specification; R16 and R17 are defined as set forth in the specification; —RC and RD have the same meaning as defined above for RA and RB except that one of them must be —H, and they are selected independently of each other and of RA and RB; R1 and R2 are each a member independently selected from the group consisting of H; F; Cl; CN; NO2; &…
