P -Selective (sp2)-C-H functionalization for an acylation/alkylation reaction using organic photoredox catalysis

p-Selective (sp2)-C-H functionalization of electron rich arenes has been achieved for acylation and alkylation reactions, respectively, with acyl/alkylselenides by organic photoredox catalysis involving an interesting mechanistic pathway.

Anionic reactions of N-(trans-2,3-diphenylaziridin-1-yl)imines and their use as 1,1-dipoles in anionic cyclizations

Reaction of N-(trans-2,3-diphenylaziridin-1-yl)imines with alkyllithiums and organocuprates afforded the desired addition products after consecutive fragmentations along with liberation of stilbene and nitrogen gas, while the reaction of N-(2-phenylaziridin-1-yl)imines under similar conditions gave an anomalous by-product. Anionic cyclizations of N-(trans-2,3-diphenylaziridin-1- yl)imines using unactivated alkenes and alkynes as acceptors proceeded smoothly, yielding cyclized products in good yields.

Conception, characterization and correlation of new marine odorants

Via a synthetic sequence consisting of PPA-mediated Friedel-Crafts acylation of veratrol (8), Clemmensen reduction, demethylation with TMSI, Williamson ether synthesis employing 3-chloro-2-(chloromethyl)prop-1-ene and in-situ ruthenium tetroxide oxidation, numerous substituted benzo[b][1,4]dioxepinones 15-27 and 2,3-dihydro-1H-5,9-di-oxacyclohepta[f]indenones 7, 13 and 14 were prepared to study their odor-structure correlation. In the course of these studies, we discovered the extremely powerful new marine odorant 7-(3′ -methylbutyl)benzo[b][1,4]dioxepin-3-one (16). On the basis of the measured odor threshold data, an olfactophore model was constructed that rationalizes the observed odor intensities, and indicates an aliphatic hydrophobe at a distance of 6.3 A from the centre of the aromatic-ring binding site.
