The present invention is concerned with compounds o formula (I)
wherein
R, R1 and R2 are independently selected from hydrogen and C1-4 alkyl;
R3 and R4 are independently selected from hydrogen, C1-6 alkyl (including cycloalkyl) and aryl (wherein the alkyl or aryl group, which latter includes benzyl, is optionally substituted by one or more atoms or groups independently selected from halogen, Ci-4 alkyl and aryl), provided R3 ≠ benzyl or substituted benzyl when R4 = H;
m is an integer of from 0 to 2;
n is an integer of from 0 to 3;
(W) is a group of formula (i), (ii), (iii), or (iv)
wherein Y is selected from oxygen, methylene and N-R5, where R5 is hydrogen, Ci-4 alkyl, or benzyl, Z and Z' are independently selected from C=O, C-S and methylene, and the chiral centre * in formula (i) or (ii) is in its (S) or (R) form or is a mixture thereof in any proportions;
