New and convenient synthesis of (R)-(+)-4,5-Dihydro-4-methyl-2(3H)-furanone and (R)-(-)-4-Bromo-3-methyl-1-O-tert-butyldimethyl-silylbutan-1-ol
摘要:
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.
