We studied 1,3,5-triazine-based amide-forming reactions that are mediated or catalyzed by various tert-amines. The representative tert-amine was trimethylamine, which has amido, 1,2,3-triazolyl, aryl, and alkyl linkers. It was found that electron-def

The structures of 1,8-bis(phenylselanyl)anthraquinone (1a), 1,8-bis(phenylselanyl)-9-methoxyanthracene (2a), and 1,8-bis(phenylselanyl)anthracene (3a) are determined by X-ray crystallographic analysis, together with the derivatives. The Se-C(i) (Ph)

Palladium-catalyzed acylation of allylic trifluoroacetates (2) using acylstannanes (1) is reported. The reaction serves as a complementary method to the previously reported acylation with acylsilane (4). In particular, the reaction is profitable in t

Amino amides react as trinucleophiles with vinyl vicinal tricarbonyl esters. Reaction of the primary amino group takes place at the β-position of the α,β-unsaturated ketone along with addition to the central carbonyl group. In a third-stage reacti

Protocols for selective acetylation of the hydroxyl groups of ginkgolide C have been developed. These acetylations have given rise to various ginkgolide C acetates and iso-ginkgolide C acetates, the latter having a rearranged skeleton resulting from

Amino lactams react as trinucleophiles with vinyl vicinal tricarbonyl esters to form tricyclic derivatives. Products of particular interest resulting from this reaction sequence are 2-azadethiapenams and 3-azadethiacephams
