Despite their simplicity and synthetic usefulness, reactions of 1, 3-dicarbonyl dianions are
often problematic, since they represent highly reactive compounds (low reactivity matching) …

Despite their simplicity and synthetic usefulness, cyclisation reactions of 1, 3‐dicarbonyl
dianions with 1, 2‐dielectrophiles are problematic, since both dianions and 1, 2 …

The present personalized account aims to highlight 1, 1-diacylcyclopropanes as synthetic
building blocks or target molecules. The chemistry presented includes cyclization reactions …

A pentafluorophenylammonium triflate (PFPAT) catalyst (5 mol%) successfully promoted C-
acylation of enol silyl ethers with acid chloride to produce various β-diketones (12 examples; …

A general method to assemble multi-substituted chiral piperidines was developed, inspired
by the biosynthesis of piperidine natural products. In biosynthesis, Δ1-piperideine 4 plays a …

Reaction of (Z)-1, 4-diketones with various functionalized nitroalkanes in the presence of
DBU gives 4-alkylidenecyclopent-2-en-1-ones with E selectivity. A cyclopentadienone …

We developed an efficient, practical, robust method for the regio-and stereoselective
preparation of (E)-ketene trimethylsilyl acetals (KSAs) derived from tert-butyl esters 1. The …

Conjugated addition of primary nitroalkanes to α, β-unsaturated ketones or α, β-unsaturated
esters, in the presence of two equivalents of DBU, allows the one-pot prepration of γ …

Abstract A new C, O‐cyclodialkylation of dilithiated cyclic β‐keto esters and β‐keto sulfones
with 1, 4‐dibromo‐2‐butene is reported which results in regio‐and diastereoselective …

The Lewis acid mediated cyclization of epoxides with 1, 3‐bis (trimethylsilyloxy)‐1, 3‐
butadienes, electroneutral equivalents of 1, 3‐dicarbonyl dianions, results in the formation of …
