alkanolamines, that have both amines and alcohols as reactive functional groups. Achieving 100% selectivity for O-formyl and O-acyl protection of alkanolamines is one of the examples of such reactions. To avoid protection and deprotection steps and overcome this problem, a novel chemoselective, efficient, and simple protocol for functional group protection as O-formylation and O-acylation of alkanolamines and

α-Cyclodextrin complexation of 3-O2NC6H4O(CH2)nNH2 inhibits by 40 and 15%, respectively, the efficiency of base-catalyzed and uncatalyzed photo-Smiles rearrangement for n = 2; α-CD complexation inhibits the photorearrangement efficiency of n = 3 by 40% in the base-catalyzed regime but enhances the efficiency by 67% in the uncatalyzed regime.

dependence on hydroxide ion concentration, but the mechanism involving hydroxide ion does not involve acid-base catalysis. The reactions take place from the triplet excited states of the nitrophenyl ethers. Analysis of quantum yields and kinetics is consistent with an electron hole transfercatalysis mechanism.
