Benzodiazepine derivatives of formula (I): (I) wherein: each of R1 and R2 is independently H or halo; either (i) T is N, Z is C, ---a--- and ---c--- are bonds, and ---b--- and ---d--- are absent; or (ii) T is C, Z is N, ---b--- and ---d--- are bonds, and ---a--- and ---c--- are absent; each of R3 and R4 is independently halo, -OR6, -NR6R7, -COR8, -C(O)OR8, -CON(R8)2 or -R6; R5 is H or halo; each of R6 and R7 is independently H or a group selected from C1-C6 alkyl, C3-C10 cycloalkyl, C6-C10 aryl, 4- to 10-membered heterocyclyl and 4- to 10-membered heteroaryl, the group being unsubstituted or substituted; R8 is H or C1-C6 alkyl, each R8 being the same or different when two are present; n is 0 or 1; and one of V, W, X and Y is N or CH and the other three are CH; and the pharmaceutically acceptable salts thereof are inhibitors of RSV and can therefore be used to treat or prevent an RSV infection.

The application of Reformatsky and Blaise reactions for the preparation of a diverse set of valuable intermediates and heterocycles in a one-pot protocol is described. To achieve this goal, a greener activation protocol for zinc in flow conditions has been developed to introduce this metal efficiently into α-bromoacetates. The organozinc compounds were added to a diverse set of ketones and nitriles to obtain a wide range of functional groups and heterocyclic systems.
PROCESS FOR PRODUCTION OF 2,3'-BIPYRIDYL-6'-ONE
-
Page/Page column 13, (2009/12/07)
A production process where 2,3'-bipyridyl-6'-one can be produced in high purity at low cost on an industrial scale without using an expensive catalyst or special equipment is provided. A process for producing 2,3'-bipyridyl-6'-one comprises reacting an acetylpyridine derivative with at least one of compounds represented by formulae (II) to (V) to synthesize a bipyridine derivative and hydrolyzing the bipyridine derivative by one-pot preparation. In formulae (II) to (V), each of R2 to R8, X and Y represents a given group.
