Flash vacuum pyrolysis (FVP) of 3-[2-(t-butylthio)phenyl]propenoate 7 at 700 °C (0.01 Torr) unexpectedly gave a mixture of benzo[b]thiophene derivatives 5 (15%) and 8 (21%), and thiocoumarin 9 (28%). Control experiments show that thiophenoxyls (e.g.

Functionalisation of the double bond of 3-thiabicyclo[3.2.0]hept-6-ene 3, readily formed by hydrolysis of the [2+2] cycloadduct 1 of 3-sulfolene and maleic anhydride followed by oxidative bis-decarboxylation, gives tricyclic sulfones 5–7 and 9 with

Flash vacuum pyrolysis of the allyl ethers 9–11 and of the oxime ethers 15–17 at 650 °C (5 × 10–2–5 × 10–3 Torr) generates 2-(aryliminomethyl)phenoxyl radicals 4 and 1-(2-aryloxyphenyl)alkaniminyl radicals 5 respectively which can interc

In the presence of excess Bu 2 BOTf to promote anti -selectivity, an asymmetric aldol reaction with a homochiral terpenoid-derived 1,3-oxazin-2-one as the chiral control element results unexpectedly in ring cleavage by an intramolecular process to fo

Flash vacuum pyrolysis of 2-allyloxypropenoic esters (e.g. 7) gives benzo[b]furans (e.g. 32) in synthetically useful yields by sequential generation of a phenoxyl radical, cyclisation and ejection of the carboxylic ester function as a free radical le

Transposition of the dormant methyl group from C-1 in chiral oxazolidin-2-one 2 to C-7 in a six step synthetic sequence from (1R)-camphor 5 creates a novel transfigomer 4 with sufficient π-topological bias to induce excellent levels of asymmetric in

Isolation of closed 6,6-bridged aziridinofullerenes 2 by reaction of [60] fullerene with singlet oxycarbonylnitrenes is accompanied by small amounts of previously undetected closed 5,6-adducts 4 , thought to arise by trapping of triplet nitrenes. Iso
