The enantioselective total syntheses of (+)-peniciketals A and B, two members of a family of architecturally complex spiroketals, have been achieved. Key synthetic transformations comprise Type I Anion Relay Chemistry (ARC) to construct the benzannulated [6,6]-spiroketal skeleton, a Negishi cross-coupling/olefin cross-metathesis reaction sequence to generate the trans-enone structure, and a late-stage large fragment union exploiting our recently developed photoisomerization/cyclization tactic.

The total synthesis of methyl alectorialate (3) and methyl barbatolate (4) has been achieved, and the synthetic esters have been compared with naturally derived material.In addition alectorialin (decarboxylalectorialic acid) (5) and barbatolin (6) have be
