Highly enantiomerically enriched γ- and δ-lactams have been prepared by a simple and very efficient procedure that involves the asymmetric transfer hydrogenation of N-(tert-butylsulfinyl)iminoesters followed by desulfinylation of the nitrogen atom and spo

We report herein a mild and catalytic phosphonofluorination of unactivated alkenes. With catalysis by AgNO3, the condensation of various unactivated alkenes with diethyl phosphite and Selectfluor reagent in CH 2Cl2/H2O/HOAc at 40 C led to the efficient synthesis of β-fluorinated alkylphosphonates with good stereoselectivity and wide functional group compatibility. A mechanism involving silver-catalyzed oxidative generation of phosphonyl radicals and silver-assisted fluorine atom transfer is proposed.
Tertiary aminourea-catalyzed enantioselective iodolactonization
Veitch, Gemma E.,Jacobsen, Eric N.
supporting information; experimental part, p. 7332 - 7335 (2010/12/18)
Binding the anion : A highly enantioselective iodolactonization of 5-hexenoic acids has been achieved using a tertiary aminourea-catalyst (see scheme). The use of catalytic iodine in this process is critical to enhancing both the reactivity and enantioselectivity of the stoichiometric I+ source. The mechanism is proposed to involve binding of an iodonium imidate intermediate by the H-bond donor catalyst.
Synthesis and studies of piperidinone, the major metabolite of a new antidepressant drug S 3344
