Claisen rearrangement (CR) of resorcinol allyl ethers was examined. Although thermal CR gave low regioselectivity, the selectivity was much improved in the presence of a Lewis acid such as boron trichloride. This rearrangement was successfully applied to resorcinol carvonyl ethers for the regioselective introduction of a carvone unit into the resorcinol skeleton for the synthesis of phytoestrogenic miroestrols.

The desymmetrisation of resorcinol to give 3-alkoxyresorcinol derivatives can be achieved in excellent yields either from resorcinol monobenzoate and alcohols using Mitsunobu reactions followed by hydrolysis using a strong base or by using 3-iodophenylbenzyl ether as a resorcinol monobenzyl ether equivalent in reactions with alcohols catalysed by copper(I)-9,10-phenanthroline followed by ammonium formate-palladium catalysed hydrogenolysis.
Silane-functionalized ultraviolet screen precursors

, (2008/06/13)
Silane-functionalized ultraviolet screening agent precursors comprise compounds of the formula: STR1 wherein R is STR2 R1 is C1 -C6 alkyl, R2 is C1 -C6 alkyl or C2 -C6 alkanoyl, R3 is hydrogen or C1 -C6 alkoxyl, X is 0,1 or 2, y is 1,2, or 3 and x+y=3. Under ultraviolet radiation the compounds rearrange to the corresponding α-hydroxybenzophenones which protect substrates, especially transparent plastics, against degradation.
