“…Depending on the amount of the DMD (1) their sulfoxides or sulfones can be prepared in good yields. [55][56][57] We have performed the dimethyldioxirane (1) oxidation of 1-thiochromones 12 which also belong to a group of sulfurcontaining compounds with an olefinic double bond 58 (Scheme 6). Again, a completely chemoselective oxidation of the sulfur atom was observed yielding sulfoxides 13 or sulfones 14 depending on the amount of the DMD (1) used.…”

“…Sulfoxides 20 were oxidized by isolated DMD (1) to obtain sulfones trans,cis-21 and trans,trans-21. It can be concluded that we managed to synthesize all the possible oxidized products of 3-arylidene-1-thioflavanones either by isolated DMD (1) as electrophilic oxidant 55,76 or by nucleophilic oxidants. 74 trans,cis-19 …”

“…No caso de (E)-3-arilideno-1-tiocromononas 26a-e e de (E)-3-arilideno-1-tioflavan-4-onas 29a-d, o emprego de 1,3 equivalentes levou à formação dos respectivos sulfóxidos 27a-e e 30a-d em ótimos rendimentos, com a formação das sulfonas 28a-e e 31a-d correspondentes em rendimentos menores que 14% (Esquema 19) 41 . Quando foram utilizados 2,2 equivalentes de DMD as respectivas sulfonas 28a-e e 31a-d foram isoladas quantitativamente 41 .…”
