This disclosure is directed to methods of preparing organic aldehydes, each method comprising contacting a terminal olefin with an oxidizing mixture comprising:
(a) a dichloro-palladium complex;
(b) a copper complex;
(c) a source of nitrite;
under aerobic reaction conditions sufficient to convert at least a portion of the terminal olefin to an aldehyde.
A class of compounds useful in pharmaceutical compositions and methods for treating or preventing cancer is described. Analogs of Mycalolide B have been prepared and tested in breast and ovarian cancer cell lines. The compounds show utility for inhibition of survival and proliferation of tumor cells. The compounds have been shown to disrupt actin.

The aldehyde-selective oxidation of alkenes bearing diverse oxygen groups in the allylic and homoallylic position was accomplished with a nitrite-modifiedWackeroxidation. Readily available oxygenated alkenes were oxidized in up to 88% aldehyde yield and as high as 97% aldehyde selectivity. The aldehyde-selective oxidation enabled the rapid, enantioselective synthesis of an important pharmaceutical
