Derivatives o] Methylenedioxy-benzene, XXIV: Synthesis o] o-Sa]role and o/Myristicine Preparation of 2.3-methylenedioxy-allylbenzene (o-safrole) (1 d) free of isomers by reaction of 2.3-dihydroxy-allylbenzene (1 b) with Ctt2BrC1 is described. Treating 4-hydroxy-3-methoxy-allylbenzene (3 a) with potas- sium nitrosodisutfonate gives 3-methoxy-5-allyl-o-benzoquinone (4) which ist reduced to 3-methoxy-5-allyl-pyrocatechol (5) with sodium dithionite. Methylenation of 3 c ...
