The design and implementation of cascade reactions is a challenging facet of organic
chemistry, yet one that can impart striking novelty, elegance, and efficiency to synthetic …

Abstract Die Entwicklung und Umsetzung von Kaskadenreaktionen hat zu beachtlichen
neuartigen, eleganten und effizienten Synthesestrategien geführt. Als besonders …

Radical tandem reactions—and in a wider context radical dominos or cascades—have
attracted a lot of attention because of their intrinsic elegance and the construction of a broad …

Studies detailing synthetic approaches to a variety of biosynthetically related vibsanin‐type
diterpenes (ie vibsanin E, 15‐O‐methylcyclovibsanin B, 3‐hydroxy‐vibsanin E …

In the presence of a photomediator such as benzophenone, alkynes with electron-
withdrawing groups react with cycloalkanes to give vinyl cycloalkanes. The reaction involves …

Radical reaction of a series of N-(2-bromoallyl) arylcarboxamides led to the production of 4-
arylpyrrolidin-2-ones and directly reduced materials in comparable yields. A cascade …

The combination of ring closing metathesis and β-fragmentation offers an efficient entry into
(Z)-configured medium ring cycloalkenes. The fragmentation step can be effected under …

Radical ring closure reactions by intramolecular addition of a radical to a tethered double
bond afford a new cyclized radical intermediate that can be reduced, or further react with …

Lithium α-sulfinyl carbanion of 1-chloroethyl p-tolyl sulfoxide was reacted with 2-substituted
cyclohexanones to afford adducts in good yields. The adducts were treated with LDA or t …

α-Tributylstannyl radicals can be generated from the corresponding bromides or xanthates.
These radicals undergo efficient intramolecular 1, 5-cyclizations with a formyl group. The …
