An efficient, environmentally benign and unprecedented synthesis of various α-sulfenylated amides/esters has been developed under oxygen atmosphere. The reaction shows good functional group tolerance and excellent chemo/regioselectivity. All the desired products were obtained in moderate to excellent yields, even on the gram scale. Practically, the related α-thiol Weinreb amide can be readily transferred to a series of prospective compounds, and selenium atom can be introduced to the α-sites of the amides in high yields.

A homochiral porphyrin ruthenium(II) complex catalyzes the cyclopropanation of styrene derivatives with ethyl diazoacetate with good yields and moderate enantiomeric excesses (46-52%). The catalyst is also active for diazocarbonyl compound insertion into S-H bonds, but with low ee.

The antilipidemic drug clofibric acid (CPIB) exhibits antiplatelet effects. In order to examine the role of enantioselectivity and hydrophobicity, the mono(desmethyl) enantiomers of 2-(4-chlorophenoxy)propanoic acid (CPPA), related butanoate homologs, 2-(
