[11] [2] This involves a set of highly selective, exothermic reactions which occur under mild conditions; the most successful example is the azide alkyne Huisgen cycloaddition to form 1,2,3-triazoles. [12] As of 2024, Sharpless has an h-index of 130 according to Scopus. [13]
The Sharpless catalog is a list of 313 H II regions (emission nebulae) intended to be comprehensive north of declination −27°.(It does include some nebulae south of that declination as well.)
The Sharpless epoxidation is viable with a large range of primary and secondary alkenic alcohols. Furthermore, with the exception noted above, a given dialkyl tartrate will preferentially add to the same face independent of the substitution on the alkene.To demonstrate the synthetic utility of the Sharpless epoxidation, the Sharpless group created synthetic intermediates of various natural ...

Sh 2-297 (also known as Sharpless 297) is an emission nebula in the constellation Canis Major. The region was catalogued in 1959 in the extended seconded edition of the Sharpless catalogue . [ 3 ] This area is part of the Canis Major OB1 Association , and is a very active area of new star formation .
Sh 2-1, also known as Sharpless 1, is the combination of a diffuse HII emission nebula and reflection nebula in the constellation of Scorpius with Pi Scorpii at its center. It appears as a modest brightness making it one of the easier Sharpless catalog objects for amateur astronomers to view.
Sh 2-88A is an HII-type diffuse nebula excited by the type O8 star BD+25°3952. [4] Both neutral and ionized gases in Sh 2-88 are between 150 and 410 solar masses and the dust mass is about 2 to 9 solar masses. The structure been interacting with a HI interstellar bubble shaped by the stellar winds of BD+25°3952 and the blue O8.5II(f) star BD ...
