A novel protocol for the deoxyalkoxyamination of alcohols has been developed, using N-alkoxybenzenesulfonimide (NOSI) as both a sulfonyl transfer reagent and an alkoxyamine source, accessing a diverse range of N-alkoxy-N-alkylbenzenesulfonamides with excellent isolated yields. This method is characterized by metal-free reaction, scalability, and waste-balance. Chiral substrates are converted with excellent levels of stereochemical inversion. NOSI could be generated in situ during the reaction as a stable reagent if a three-component one-pot reaction was designed. Exploiting this approach to run intramolecular reactions offered various N-protected isoxazolidines. In addition, valuable O-alkyl hydroxylamines (or isoxazolidines) were obtained through a neutral strategy of desulfonylation of the products.

A series of diverse natural product-like structures have been synthesised by the use of a number of novel transannulation reactions across a cyclononene ring. Transannular cyclisations through oxygen functionality have generated a number of bicyclo[5.3.1]systems containing bridged cyclic ethers and bicyclo[5.2.2]lactones, as well as a tetrahydrofuran-containing bridged analogue of hexacyclinic acid. An unprecedented Bronsted acid mediated transannular cyclisation between proximal carbons generated bicyclo[4.3.0] nonanes which form the core of the pinguisane and austrodorane families of sesquiterpenoids. In all cases the key factor that determined the mode of reactivity was the conformation of the nine-membered ring and the distance between the reacting centres. The Royal Society of Chemistry 2011.
