Organophotoredox/palladium dual catalytic decarboxylative Csp3-Csp3coupling of carboxylic acids and π-electrophiles

A dual catalytic decarboxylative allylation and benzylation method for the construction of new C(sp3)-C(sp3) bonds between readily available carboxylic acids and functionally diverse carbonate electrophiles has been developed. The new process is mild, operationally simple, and has greatly improved upon the efficiency and generality of previous methodology. In addition, new insights into the reaction mechanism have been realized and provide further understanding of the harnessed reactivity.

Intramolecular meta photocycloaddition of conformationally restrained 5-phenylpent-1-enes. Part II: Steric and electronic effects caused by 4-mono- and 4-disubstitution

The meta photocycloaddition of 4-substituted 5-phenylpent-1-enes. 10-18, has been studied. The monosubstituted derivatives always prefer 2,6 addition, independent of the size of the substituent. For 2,6 addition two basic conformations are possible. Disubstituted compounds yield predominantly 1,3 addition with the sterically more demanding group exo. Except for the methoxymethyl and THF derivative the oxygen is found exo as a result of repulsion, while the monohydroxy derivative gives also endo which might be explained by hydrogen bonding. The products from compound 11 change from mainly endo-OH in cyclohexane to chiefly exo-OH in methanol. Much similarity is found with Diels-Alder cycloaddition.

Additions of Allylic Grignard Reagents to o-Allylphenol

Reactions of o-allylphenol (1a) with allylmagnesium chloride or bromide furnished 6-(o-hydroxyphenyl)-1-hexene (2a) and 4-methyl-5-(o-hydroxyphenyl)-1-pentene (3a), products resulting from both possible orientations of addition.A reaction of 1a and (2-methyl-2-propenyl)magnesium chloride gave only 6-(o-hydroxyphenyl)-2-methyl-1-hexene (2b).From comparisons with reactions of allylmagnesium chloride with o-allylanisole and allylbenzene, it is concluded that the metalated phenolic hydroxyl group, even though relatively remote from the double bond, assists the additions to 1a.
