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 present invention provides compounds, compositions thereof, and methods of using the same for the inhibition of CRBN, and the treatment of CRBN-mediated disorders.

The invention provides heterocyclic compounds with quaternary centers and methods of preparing compounds. Methods include the method for the preparation of a compound of Formula (II):

##STR00001##

comprising treating a compound of Formula (I):

##STR00002##

with a transition metal catalyst and under alkylation conditions as valence and stability permit.
