Virescenol homo-Favorskii rearrangement

The Favorskii-type rearrangements of chloroenamines such as (31) have received some investigation, and key results are presented in Scheme 45. Finally, the so-called homo-Favorskii rearrangement has been probed, and an example from the original work of Wenkert and coworkers is illustrated in Scheme 46. A partially successful homo-Favorskii rearrangement carried out on the diterpenoid (32 a derivative of virescenol A) is shown in Scheme 47, but the synthetic potential of this variant of the Favorskii rearrangement remains to be established.
