Abstract
October, 1960] Syntheses of a-, ß-and r-Dolabrins 1453 obtained. Hydrolysis of IV with alcoholic alkali gives a tropolone derivative (VI), Ci0Hi0O2 as colorless scaly crystals, mp 101 C, and its reduction affords f-thujaplicin, indicating that VI is the objective 5- isopropenyltropolone, which may be called f-dolabrin. pX" a value of VI is 7.17 at 25 C***. y- Dolabrin (VI) so obtained can be led back to/3-dolabrin by the same process. VI affords ...
