, p. 31 - 36 (2015)
Abstract Peptide derivatives (8 and 9) of 2-amino-2′-carboxydiphenylacetylene (1) were prepared using the Sonogashira reaction and standard peptide chemistry. As reported earlier by Kemp and Li (Ref. [1]), 8 and 9 adopt anti-parallel β-sheet conformations

Heteroacenes are potentially important materials for organic electronics and their syntheses are of topical interest. Herein we report the development of a catalytic, redox-neutral reaction for the synthesis of the 5,10-dihydroindolo[3,2-b]indole class of
Diversely Substituted Quinolines via Rhodium-Catalyzed Alkyne Hydroacylation
Neuhaus, James D.,Morrow, Sarah M.,Brunavs, Michael,Willis, Michael C.
, p. 1562 - 1565 (2016/05/02)
The Rh-catalyzed hydroacylative union of aldehydes and o-alkynyl anilines leads to 2-aminophenyl enones, and onward to substituted quinolines. The mild reaction conditions employed in this chemistry result in a process that displays broad functional group

The invention discloses a kind of type I of the pyrimidine or pyridine pyridine ketone compound and its preparation and application, which belongs to the technical field of pharmaceutical preparation. The compounds have high-efficient and selectively inhibit the cell cycle dependent kinases (Cdks) CDK4 and CDK6 active, and then by inhibiting CDK4/CDK6 prevent tumor cell division. Therefore, the compounds of this invention can be used for CDK4 and CDK6 the involved in cell cycle control disorders result in various diseases, especially suitable for the treatment of malignant tumors.

Gold(i) catalyzed tandem cyclization of propargylic esters to 4-acyloxy-1,2-dihydroquinolines

supporting information, p. 6942 - 6945 (2016/06/06)
An effective synthetic protocol for structurally diverse 4-acyloxy-1,2-dihydroquinoline compounds has been accomplished by a gold(i)-catalyzed tandem [3,3]-rearrangement and intramolecular hydroamination of propargylic esters, affording the desired products in good yields. Moreover, the asymmetric variant of this cyclization has also been achieved using a chiral nitrogen acyclic carbene (NAC) gold(i) complex. These products have application in the enantioselective synthesis of an aromatase inhibitor within three simple steps.
Pd/C-catalyzed cyclizative cross-coupling of two ortho-alkynylanilines under aerobic conditions: Synthesis of 2,3′-bisindoles

, p. 2259 - 2271 (2007/10/03)
Intermolecular Pauson-Khand reaction of various 1-alkynes with 4-exo-methylenepiperidine and -cyclohexane derivatives to give corresponding spirocyclopentenones was investigated. The reaction of m- and p-substituted arylalkynes furnished corresponding spirocyclic compounds in good yields, while that of o-substituted arylalkynes and 1-hexyne proceeded in nil to moderate yield.
