(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 …

Steroids belong to an essential class of bioactive natural products owing to their ability to
enter cell membranes and bind to nuclear and membrane receptors. The steroidal system …

Direct approach to indoles: The title reaction generates cyclohepta [b] indole derivatives in a
single step at room temperature (see scheme). Exclusion of air or moisture is not required …

Developing efficient and general strategies to construct skeletally complex and diverse
polycyclic skeletons is important for both synthesis of natural products and chemical biology …

Substituted furfuryl alcohols are extraordinarily versatile starting materials in synthesis. They
are precursors to furanoxonium ion intermediates which are implicated in the Piancatelli …

Observation of an unexpected, Lewis acid promoted displacement of latent reactive γ‐amino
group on cyclopentenone presented unparalleled opportunity for enone functionalization …

Described is a concise total synthesis of (−)-ambiguine P, a cycloheptane-containing
member of the hapalindole alkaloids. The challenging pentacyclic framework of the natural …

The long-standing and continuous interest in efficient synthetic approaches to
cyclopentanoids stems from their value as building blocks in organic chemistry and their …

Abstract A recently developed (4+ 3) cycloaddition between dienes and furfuryl alcohols, as
precursors of oxyallyl‐type cations, has been used as a key step in the racemic syntheses of …

Abstract A convenient zinc‐promoted [4+ 3] cycloaddition of a carbonyl ene–yne with simple
dienes was first achieved. This reaction provided an efficient strategy to prepare various …
