Conspectus Tetracyclic diterpenoids (C20) mainly refer to the plant terpenoids bearing
biogenetically related carbon skeletons derived from copalyl diphosphates (ent-CPP and …

This work reports the total syntheses of Isodon diterpenes trichorabdal A and maoecrystal Z
via a common bicyclo [3.2. 1] octane intermediate, which chemically bridges the two distinct …

A type II intramolecular oxidopyrylium‐mediated [5+ 2] cycloaddition reaction allows the
efficient and diastereoselective formation of various highly functionalized and synthetically …

A new TiIII‐mediated reductive epoxide‐opening/Beckwith–Dowd rearrangement process
efficiently assembles the bicyclo [3.2. 1] octane framework of highly oxidized grayanane …

A solvent-dependent oxidative dearomatization-induced divergent [5+ 2] cascade approach
to bicyclo [3.2. 1] octanes was described. This novel protocol enables a facile synthesis of a …

[5+ 2] Cycloaddition reactions have attracted increasing attention from the chemistry
community owing to their utility in the field of natural product synthesis. Recently, a number …

Efficient formal syntheses of (±)-Asterisca-3 (15), 6-diene, a natural product with a bicyclo
[6.3. 0] undecane skeleton, and (±)-Pentalenene, a natural product with a tricyclo [6.3. 0.04 …

The domino effect: The combination of two multiple bond‐forming transformations; a
consecutive Wolff rearrangement/acylketene‐trapping cross metathesis reaction and a …

A one-pot cascade process of benzyl enoldiazoacatates, initiated by dirhodium (II)-catalyzed
intramolecular cyclopropene formation, occurs via a subsequent Buchner reaction and Cope …

(4+ 3) Cycloadditions have been widely applied in synthesis, and in this review article, we
summarize some of the more recent applications, including formal (4+ 3) cycloadditions, in …
