Enantioselective total synthesis of (+)-stoechospermol 2, a representative of spatane diterpenes having a cis,anti,cis-tricyclo[5.3.0.0(2,6)]decane skeleton, was achieved by employing a stereo- and regioselective intramolecular (2+2) photocycloaddition of (S)-gamma-hydroxymethyl-gamma-butenolide-derived ester 10.
