In 1956, \textit{H. L. Alder} [Research Problem 4, Bull. Am. Math. Soc. 62 (1956), p. 76] conjectured that the number of partitions of \(n\) into parts differing by at least \(d\) is greater than or equal to that of partitions of \(n\) into parts \(\equiv \pm 1 \pmod {d+3}\).

Dehydrogenative Diels–Alder Reaction
Organic Letters, 2011The dehydrogenative cycloaddition of dieneynes, which possess a diene in the form of a styrene moiety and a dienophile in the form of an alkyne moiety, produces naphthalene derivatives when heated. It was found that a key requirement of this process is the presence of a silyl group attached to the alkyne moiety, which forces a dehydrogenation reaction ...

RESOURCE POTENTIAL OF BLACK ALDER AND GRAY ALDER LEAVES
Vestnik Farmacii, 2021Annual renewable resource potential of medicinal plant materials in the Republic of Belarus - Black alder leaves and Gray alder leaves - has been studied. It was found that average annual supply of black alder leaves for the last 6 years was 7845898,5 tons and gray alder leaves - 733257,5 tons. The stock of black alder leaves is almost 10 times as high

The Diels–Alder reaction, inverse electronic demand Diels–Alder reaction, as well as the hetero-Diels–Alder reaction, belong to the category of [4+2]-cycloaddition reactions, which are concerted processes.

The Alder ene reaction, also known as the hydro-allyl addition, is addition of an enophile to an alkene (ene) via allylic transposition. The four-electron system including an alkene π-bond and an allylic C–H σ-bond can participate in a pericyclic reaction in which the double bond shifts and new C–H and C–C σ-bonds are formed.

o-Fluoranil Chemistry: Diels–Alder versus Hetero-Diels–Alder Cycloaddition
The Journal of Organic Chemistry, 2008The title quinone undergoes [4 + 2] cycloadditions in two ways, Diels-Alder on the ring and hetero-Diels-Alder by attack at the oxygens. The latter mode of reaction is strongly favored thermodynamically, but there is a kinetic bias favoring the normal Diels-Alder addition that often prevails, especially with cycloaddends that are not electron-rich.

Diels-Alder reaction, inverse electronic demand Diels-Alder reaction, hetero-Diels-Alder reaction
2002The Diels-Alder reaction, reverse electronic demand Diels-Alder reaction, as well as the hetero-Diels-Alder reactions, belong to the category of [4+2] -cycloaddition reactions, which is a concerted process. The arrow-pushing here is merely illustrative.
