A total synthesis of the tetra-Z-isomer (1, ‘prolycopene’) of lycopene found in fruits of the Tangerine tomatoLycopersicon esculentum, based on: (i) elaboration of the2Z, 6E-carbinol (4) from a Pd-coupling reaction between the vinyl bromide (2) and the Z-enynol(3) (ii) successive Wittig reactions between (6) and (7), [leading to (8)] and between (8) and (6), and (iii) partial catalytic hydrogenation
