Page/Page column 49; 51-52, (2008/06/13)
Compounds of formula (I) are inhibitors of histone deacetylase activity, and are useful in the treatment of, for example, cancers: formula (I) wherein Y1 is a bond, -(C=O)-, -S(O2)-, -C(=O)O-, -OC(=O)-, -(C=O)NR3, -NR3(C=O)-, -S(O2)NR3-, -NR3S(O2)-, or -NR3(C=O)NR5-, wherein R3 and R5 are independently hydrogen or optionally substituted (C1-C6)alkyl, L1 is a divalent radical of formula -(Alk1)m(Q)n(Alk2)p- wherein m, n, p, AIk1, AIk2 and Q are as defined in the claims; z is O or 1 ; A represents an optionally substituted mono-, bi- or tri-cyclic carbocyclic or heterocyclic ring system; -[Linker]- represents a divalent linker radical; R is a radical of formula (X) or (Y); wherein R1 is a carboxylic acid group (-COOH), or an ester group which is hydrolysable by one or more intracellular carboxylesterase enzymes to a carboxylic acid group; R4 is hydrogen; or optionally substituted C1-C6 alkyl, C3-C7cycloalkyl, aryl, aryl(C1-C6 alkyl)-, heteroaryl, heteroaryl(C1-C6 alkyl)-, -(C=O)R3, -(C=O)OR3, or -(C=O)NR3 wherein R3 is hydrogen or optionally substituted (C1-C6)alkyl, C3-C7 cycloalkyl, aryl, aryl(C1-C6 alkyl)-, heteroaryl, or heteroary(C1-C6 alkyl)-; R41 is hydrogen or optionally substituted C1-C6 alkyl; and B is a monocyclic heterocyclic ring of 5 or 6 ring atoms wherein R1 is linked to a ring carbon adjacent the ring nitrogen shown, and ring B is optionally fused to a second carbocyclic or heterocyclic ring of 5 or 6 ring atoms in which case the bond shown intersected by a wavy line may be from a ring atom in said second ring.

Compounds of formula (I) are inhibitors of histone deacetylase activity, and are useful in the treatment of, for example, cancers, wherein R1 is a carboxylic acid group (-COOH), or an ester group which is hydrolysable by one or more intracellular carboxyesterase enzymes to a carboxylic acid group; R2is the side chain of a natural or non-natural alpha amino acid; Y is a bond, -C(=O)-, -S(=O)2-, -C(=O)O-, -C(O)NR3-, -C(=S)-NR3 , -C(=NH)NR3 or -S(=O)2NR3- wherein R3 is hydrogen or optionally substituted C1-C6 alkyl; L1 is a divalent radical of formula -(Alk1)m(Q)n(Alk2)p- wherein m, n and p are independently 0 or 1 , Q is (i) an optionally substituted divalent mono- or bicyclic carbocyclic or heterocyclic radical having 5 - 13 ring members, or (ii), in the case where both m and p are 0, a divalent radical of formula -X2-Q1- or -Q1-X2- wherein X2 is -O-, S- or NRA- wherein RA is hydrogen or optionally substituted C1-C3 alkyl, and Q1 is an optionally substituted divalent mono- or bicyclic carbocyclic or heterocyclic radical having 5 - 13 ring members, AIk1 and AIk2 independently represent optionally substituted divalent C3-C7 cycloalkyl radicals, or optionally substituted straight or branched, C1-C6 alkylene, C2-C6 alkenylene ,or C2-C6 alkynylene radicals which may optionally contain or terminate in an ether (-O-), thioether (-S-) or amino (-NRA-) link wherein RA is hydrogen or optionally substituted C1-C3 alkyl; X1 represents a bond; -C(=O); or -S(=O)2-; -NR4C(=O)-, -C(=O)NR4-, -NR4C(=O)NR5- , -NR4S(=O)2-, or -S(=O)2NR4-wherein R4 and R5 are independently hydrogen or optionally substituted C1-C6 alkyl; z is 0 or 1 ; A represents an optionally substituted mono-, bi- or tri-cyclic carbocyclic or heterocyclic ring system wherein the radicals R1R2NH-Y-L1-X1-[CH2]Z- and HONHCO-[LINKER]- are attached different ring atoms; and -[Linker]- represents a divalent linker radical linking a ring atom in A with the hydroxamic acid group CONHOH, the length of the linker radical, from the terminal atom linked to the ring atom of A to the terminal atom linked to the hydroxamic acid group, is equivalent to that of an unbranched saturated hydrocarbon chain of from 3-10 carbon atoms.
REACTION OF BENZOTHIOPHENE-5- AND 6-METHANOLS WITH n-BUTYLLITHIUM. DIRECTED LITHIATION IN THE BENZENE RING
Cross, Peter E.,Dickinson, Roger P.
, p. 2391 - 2400 (2007/10/02)
The preparation of 3-methylbenzothiophene-6-methanol (3) is described.Treatment of 3 with n-butyllithium followed by CO2 gave, in addition to the expected 2-carboxylic acid 2, a substantial quantity of the lactone 11 formed via lithiation at the 7-position.It was concluded that lithiation at 7-position is favoured by a co-operative effect of the anion of the alcohol and the ring sulphur atom, as well as the 3-methyl group which reduces the rate of lithiation at the 2-position.In the case of compounds in which the alcohol group is at the 5-position or which lack the 3-methyl group, lithiation in the benzene ring was much less favoured .
