Microwave promoted selective preparation of acetals and esters from aldehydes

A new selective method of acetalization of aldehydes and cyclic ketones with 1,2-diols or alcohols catalyzed by iodine under microwave irradiation is reported. Depending upon the reaction conditions further oxidation of the arylidene acetals takes place in the system leading to the formation of products like iodoester 2 and hydroxy esters 3, 4 and 5. Both unsubstituted (1a) and substituted arylidene acetal with electron releasing group (1d) give high yield of iodoester 2 (70-80%) whereas the arylidene acetal substituted with an electron withdrawing group such as NO2 (1b) gives a low yield of the corresponding iodoester (2b, 25%).

β-Hydroxycyclopentylperoxide compounds and the use thereof

Novel peroxide compounds and the use thereof. In particular, the present invention concerns β-hydroxycyclopentylperoxide compounds of the general formula: STR1 wherein R1 represents hydrogen or an organic residue of 1 to 9 carbon atoms. These novel peroxide compounds are useful as an intermediate in the production of glutaraldehydes.

DIHYDROPYRAN DERIVATIVES. VI.* REACTION OF FUNCTIONAL DERIVATIVES OF 3,4-DIHYDROPYRAN WITH ALCOHOLS

The reaction of functional derivatives of 3,4-dihydropyran with alcohols and glycols in the presence of hydrochloric acid leads to acetals with various structures, formed both through addition of the alcohols to the double bond and through alcoholysis leading to opening of the dihydropyran ring with the formation of glutaraldehyde acetals.
