Disclosed herein are analogs and derivatives of aleutianamine and methods of making the same. Also disclosed herein are methods of treating pancreatic cancer comprising administration of aleutianamine or its analogs.
Abstract:
Described here are transition metal-catalyzed enantioselective arylation and vinylation reactions of α-substituted lactams, such as γ-lactams. The use of various electrophiles and ligands are described, and result in the construction of α-quaternary centers in good yields (up to 91% yield) and high enantioselectivities (up to 97% ee).
Abstract:

Abstract:
This invention provides efficient and scalable enantioselective methods that yield 2-alkyl-2-allylcycloalkyanone compounds with quaternary stereogenic centers. Methods include the method for the preparation of a compound of formula (I): comprising treating a compound of formula (II) or (III): with a palladium (II) catalyst under alkylation conditions.
Abstract:
The present invention describes chemical systems and methods for silylating heteroaromatic organic substrates using at least alkoxide base, preferably a potassium alkoxide base and at least one organodisilane and (b) at least one alkoxide base. Both methods and compositions for affecting these transformations are disclosed.
Abstract:
The present invention is directed to a mild, efficient, and general direct C(sp)-H bond silylation. Various embodiments includes methods, each method comprising or consisting essentially of contacting at least one organic substrate comprising a terminal alkynyl C—H bond, with a mixture of at least one organosilane and an alkali metal hydroxide, under conditions sufficient to form a silylated terminal alkynyl moiety. The methods are operable in the substantially absence of transition-metal compounds. The systems associated with these methods are also disclosed.
