A convenient partial synthesis of the lactone (+)-10 is reported starting from the readily available methyl (S)-(+)-3-hydroxy-2-methylpropanoate (+)-1. Furthermore, an efficient three step route to the optically active saturated isoprene unit (-)-13 in high yield starting from the lactone (+)-10 is reported for the first time.
