A reactive diene, ethyl 2-methylene-4-(pent-3-oxy)but-2-enoate, bearing electron-withdrawing carboxy and electron-donating pentoxy substituents is prepared and trapped in situ by a variety of dienophiles to form [4+2] cycloaddition products. Diels–Alder reaction of this diene with fumarate esters gives multiply substituted cyclohexenes that are useful for building the scaffold of oseltamivir.

The present disclosure relates to bifunctional compounds, which find utility to degrade and (inhibit) Androgen Receptor. In particular, the present disclosure is directed to compounds, which contain on one end a cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds Androgen Receptor, such that Androgen Receptor is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of Androgen Receptor. The present disclosure exhibits a broad range of pharmacological activities associated with compounds according to the present disclosure, consistent with the degradation/inhibition of Androgen Receptor.
