Thiyl Radicals in Organic Synthesis
TL;DR: The thiol−olefin cooxidation process was applied to the total synthesis of antimalarial agent yingzhaosu A and was extended to include the more challenging 1,5-dienes, from which six-membered ring endoperoxides can be obtained.

Conformational analysis. 130. MM2. A hydrocarbon force field utilizing V1 and V2 torsional terms
TL;DR: An improved force field for molecular mechanics calculations of the structures and energies of hydrocarbons is presented in this paper, where the problem of simultaneously obtaining a sufficiently large gauche butane interaction energy while keeping the hydrogens small enough for good structural predictions was solved with the aid of onefold and twofold rotational barriers.

Rules for ring closure
TL;DR: The endocyclic closure of nucleophilic centres to polarized double bonds to give five-membered rings is impeded by restrictions of geometry; these restrictions can be overcome in acid through the generation of oxonium or protonated forms.
