Abstract
1,2‐Dioxetanes bearing different 3‐phenoxy substituents add to aldehydes to give 1,2,4‐trioxanes in yields of 17–75% depending on the nature of the para‐phenyl substituent. Illustrations of this new reaction are described.

## Abstract The dye‐sensitized photo‐oxygenation of 1,3‐dimethylindole in the presence of aldehydes initially generates a zwitterionic peroxide which condenses with the carbonyl function to give the corresponding __cis__‐fused 1,2,4‐trioxanes. Acetaldehyde gives a pair of diastereomers, one of whos
The vibrational spectra of some 1,2,4-trioxanes present two characteristic bands at 790 and 880 cm-'. On the basis of "0-isotopic substitution and comparison with analogous compounds, these bands have been assigned to coupled C-0 and 0-0 stretching modes of the C-0-0 element. ## Introduction. -Ev
The three dihydronaphtho[l,2,4]trioxines e l l have been synthesized and two of them converted to the five carbamate and ester derivatives 12-16 (Schemes I and 2). The resulting new trioxanes together with two already known and ascaridole (7) were tested for antimalarial activity against the sensiti
