In recent decades, transient and highly reactive ortho-quinodimethanes (o-QDMs), ortho-
quinone methides (o-QMs) and aza-ortho-quinone methides (aza-o-QMs) have attracted …

In this article strategies for the design and synthesis of natural product analogues are
summarized and illustrated with some selected examples. Proven strategies include …

The synthetic utility and potential power of the Diels–Alder (D–A) reaction in organic
chemistry is evident. These significances have been extended to the synthesis of a plethora …

Herein, we describe the first catalytic asymmetric intramolecular [4+ 2] cycloaddition of in situ
generated ortho‐quinone methides. In the presence of a confined chiral imidodiphosphoric …

Abstract Development of new methods of heterocyclic synthesis is still a topical issue. In this
connection, the trend related to the use of highly reactive o-quinone methides for the …

Herein presented is a review of the reactivity and synthetic utility of ortho-quinone methides
and ortho-quinone methide imines. These versatile intermediates have received significant …

Covering: up to January 2020 [4+ 2] type terpenoid dimers are natural products
biosynthetically derived from [4+ 2] cycloaddition between two terpenoid monomers. They …

Due to experiencing a challenging dearomatization process, the aromatic sigmatropic
rearrangement of allyl naphthyl ethers is a difficult yet efficient method to build useful …

The spirocyclic motif is abundant in natural products and provides an ideal three-
dimensional template to interact with biological targets. With significant attention historically …

An asymmetric allylic dearomatization reaction of 1-nitro-2-naphthol derivatives with Morita–
Baylis–Hillman (MBH) adducts has been developed. By utilizing Pd catalyst derived from Pd …
