substituents, respectively, which is not capable of reducing the oxidizing<br />
agents such as Tollens reagents (AgO), of formula<br />
D is of formula<br />
wherein R 2 may be hydroxyl (-OH), alkoxy (-0-R'), wherein R' is a C1-C8 linear<br />
or branched, saturated or unsaturated alkyl chain and is preferably a methoxy<br />
group (-OCH 3 ), or R 2 is -N-R 3 2, wherein each R 3 may be independently H, a<br />
C1-C8 linear or branched, saturated or unsaturated alkyl chain, optionally<br />
substituted with an A group, wherein the A group may be a C3-C6 saturated or<br />
partially unsaturated cyclic- or heterocyclic ring or a C5-C6 aromatic or<br />
heteroaromatic ring, which cyclic or heterocyclic, aromatic or heteroaromatic<br />
ring may be optionally substituted at any available position with one or more of<br />
hydroxyl (-OH), C1-C8 linear or branched, saturated or unsaturated alkyl chain,<br />
C1-C8 linear or branched, saturated or unsaturated alkoxy carbon chain,
