Avery efficient and mild procedure for preparation of silyl ethers from benzylic, allylic, propargilic alcohols, phenols, naphtoles and some of phenolic drugs with trimethylsilylchloride (TMSCl), triethylsilylchloride (TESCl) and t-buthyldimethylsilyl chloride (TDSCl) ethers in the presence of Fe(HSO 4)3/Et3N in roomtemperature in excellent yields is reported. This procedure also allows the excellent selectivity for silylation of alcohols and phenols.

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.
