Regioselective copper-catalyzed aminoborylation of styrenes with bis(pinacolato)diboron and diazo compounds

A Cu(i)-catalyzed aminoborylation reaction of styrenes is reported. In this transformation, diazo compounds are used as the electrophilic amination agent. The in situ generated benzylcopper species is trapped by the electrophilic nitrogen terminus of the diazo substrate to afford borylated hydrazones in a regioselective manner.

Reactions of Azines. 12. Preparation and Reactions of Triphenylphosphonium Bromide

Preparation of triphenylphosphonium bromide (13), triphenylphosphonium iodide (15), and their corresponding ylides 14 and 16 was accomplished.The reaction of 14 with diphenylketene gave 2-methyl-4,9-diphenyl-9-(methoxycarbonyl)-4,9-dihydropyrazoloisoquinoline (19/20).The reaction of 16 with phenyl isocyanate gave 6,7-dimethyl-3-methoxy-1,3-diphenyl-1H-imidazopyrazol-2(3H)-one (27b), 2,3-dimethyl-9-(methoxycarbonyl)-9-phenyl-4,9-dihydropyrazoloquinazoline (30), and 2,3-dimethyl-9-phenylpyrazoloquinazoline (31).Phenylacetoxyketene, on reacting with triphenylphosphorane (35), gave 2-methyl-4,9-diphenylpyrazoloisoquinoline (40).Carbon disulfide with ylide 16 gave the 2,3-dimethyl-9-(methoxycarbonyl)-9H-pyrazolobenzothiazine (45) and desaurine (42) as well as the trans-5,10-bis(methoxycarbonyl)-5,10-diphenyldipyrazolodiazadithiocine (46).Confirmation of the structures 31, 42, and 46 was obtained by crystallographic analyses.
