The present invention relates to a method for preparing 3- [ ( 4S ) -8-bromo-l-methyl-6- (pyridin-2-yl ) -4H-imidazo [1,2- a] [ 1, 4 ] benzodiazepin-4-yl ] -propionic acid methyl ester starting from 3- [ (3S) -7-bromo-2-oxo-5- (pyridin-2-yl ) -2, 3-dihydro-lH- [ 1, 4 ] -benzodiazepin-3-yl ] propionic acid methyl ester, and novel compounds useful as intermediates in said method, i.e., (3S) -3- [ 7-bromo-2- ( 2, 2-dimethoxypropylamino ) -5-pyridin-2-yl-3H- benzo [e] [ 1, 4 ] diazepin-3-yl ] propionic acid methyl ester.
‘Rhaz'zmatazz: A totalsynthesis of (−)‐rhazinilam and the first asymmetric totalsynthesis of (−)‐rhazinicine were accomplished by using constructing the indolizinone core through the gold‐catalyzed cyclization of a fully elaborated linear ynamide. The scope and generality of this cascade reaction for the construction of highly substituted indolizinones were also investigated.

Reaction of pyrrole‐2‐carboxamides with Selectfluor in MeCN/water (4:1) affords 2‐hydroxy‐5‐oxopyrrole‐2‐carboxamides in yields of up to 80 %. A variety of sensitive functional groups is tolerated, among them aldehydes and alkynes. The new method also works in the presence of allyl groups and appears to be superior to the use of singlet oxygen. Reaction of the monobrominated dihydropyrrolo[1,2‐a]pyrazinone
