Rhodium/Yanphos-Catalyzed Asymmetric Interrupted Intramolecular Hydroaminomethylation of trans-1,2-Disubstituted Alkenes

The first interrupted asymmetric hydroaminomethylation reaction was developed. The challenging trans-1,2-disubstituted olefins were employed as substrates, and a series of valuable chiral pyrrolidinones and pyrrolidines were obtained in high yields with high regioselectivities and excellent enantioselectivities. Several synthetic transformations were conducted, demonstrating the high synthetic utility of our method. A creative route for the synthesis of vernakalant and Enablex was also developed.

Substrate-directable heck reactions with arenediazonium salts. The regio- and stereoselective arylation of allylamine derivatives and applications in the synthesis of naftifine and abamines

The palladium-catalyzed, substrate-directable Heck-Matsuda reaction of allylamine derivatives with arenediazonium salts is reported. The reaction proceeds under mild conditions, with excellent regio- and stereochemical control as a function of coordinating groups present in the allylamine substrate. The distance between the olefin moiety and the car-bonylic system seems to play a key role regarding the regiocontrol. The method presents itself as robust, as simple to carry out, and with wide synthetic scope concerning the allylic substrates and the type of arenediazonium employed. The synthetic potential of the method is illustrated by the short total syntheses of the bioactive compounds naftifine, abamine, and abamine SG.

Phenyl substituted dipeptide amides

The invention relates to novel substituted tyrosyl alanine dipeptide amides of the formula: STR1 and the pharmaceutically acceptable acid addition salts thereof wherein R1 is hydrogen, lower alkyl, hydroxy, --OCO2 lower alkyl, lower alkoxy, --O(CH2)n -phenyl with the phenyl optionally substituted by halogen, --NO2, --CN, --NH2 or lower alkyl wherein n is 1 to 4; R2 and R3 represent lower alkyl, halogen, or lower alkoxy, or either one of R2 or R3 is hydrogen and the other is lower alkyl, lower alkoxy or halogen; R4, R5, R6, R7, R8, and R9 may be the same or different and represent hydrogen or lower alkyl; R10 is selected from the group consisting of where ALK represents alkylene, thioalkylene, oxyalkylene, having 1 to 5 carbon atoms; alkenylene and alkynylene having 2 to 4 carbon atoms; and X represents pyridyl, pyrimidinyl, 9H-fluoren-9-yl, diphenylmethyl, thienyl, carboxy, lower alkoxy carbonyl, substituted phenyl wherein the phenyl substituent is amino, hydroxy, halogen, nitro, methylenedioxy, lower alkyl, carboxy, lower alkoxycarbonyl, lower alkoxy, carboxamide, diloweralkylamino or X represents phenyl, when ALK is not alkylene; or R10 is STR2 where p and q are independently 1 to 4; or R9 and R10 together with N is STR3 where r and t are independently 1 to 4; v represents an asymmetric carbon that may be racemic or have the D or L configuration; w represents an asymmetric carbon when R7 and R8 are not the same that may be racemic or have the D or L configuration. These compounds are useful as analgesic and/or antihypertensive compounds.
