Palladium-catalyzed carboamination reactions of N-allylguanidines bearing cleavable N-cyano or N-arylsulfonyl protecting groups are described. The reactions afford cyclic guanidine products in good yield, and transformations of substrates bearing internal alkenes proceed with high diastereoselectivity. Deuterium labeling studies indicate these transformations proceed via anti-aminopalladation pathways.

Strained, tertiary, allylic, amine 2-benzyl-2-azabicyclo[2.2.1]hept-5-ene reacts with in situ generated carbodiimides in a 1,3-diaza-Claisen rearrangement to afford structurally interesting bicyclic guanidines. Use of more electron deficient carbodiimides makes these rearrangements more facile; however, there are not sufficient methods for the synthesis of highly electron deficient carbodiimides. Herein reported is the exploration of the synthesis of such carbodiimides from parent ureas and isothioureas and their use in 1,3-diaza-Claisen rearrangements.

The signal transducer and activator of transcription 3 (STAT3) oncogene is a promising molecular target and its inhibitors have great potential as anticancer drugs. To identify novel and STAT3-selective inhibitors, a virtual screening based on Specs and M
Regiospecific synthesis of N-sulfonyl derivatives of 3,5-diamino-1H-1,2,4-triazole and 2,5-diamino-1,3,4-thiadiazole

Condensation of the S,S-dimethyl N-(alkylsulfonyl)carbondithioimidates 1 with aminoguanidine bicarbonate and hydrazinecarbothioamide leads to the regiospecific synthesis of N-sulfonyl derivatives of 3,5-diamino-1H-1,2,4-triazole 2 and 2,5-diamino-1,3,4-thiadiazole 3, respectively.
