Naganaboina, Ram Tilak published the artcileTrifluoroacetic acid-promoted Michael addition-cyclization reactions of vinylogous carbamates, Formula: C10H11NO4, the publication is Organic & Biomolecular Chemistry (2014), 12(21), 3366-3370, database is CAplus and MEDLINE.
A simple and efficient methodol. was developed for the synthesis of pyrrolobenzoxazine and 3-arylamino coumarin derivatives promoted by trifluoroacetic acid. The initial step in the current protocol involves a Michael addition of the 1,4-benzoxazinone derivatives, a novel class of vinylogous carbamates to the Michael acceptors and subsequent cyclization.
