Highly enantioselective asymmetric hydrogenation of readily accessible olefins, (E)- and (Z)-[1-(toluene-4-sulfonyl)-1,2,3, 4-tetrahydro-1H-benzo[b]azepin-5-ylidene]acetic acid (4a and 4b, respectively) and [1-(toluene-4-sulfonyl)-2, 3-dihydro-1H-benzo[b]azepin-5-yl]acetic acid (4c), is presented as
Addition of an N-substituted indole without any substitution in the 2 and 3 positions to 1 ,Gnaphtoquinone leads to the expected, 2-(3-indolyl)-l,4-naphtoquinone. The latter reacts with some dienophiles via a Diels -Alder reaction and gives new N-substituted naphto-[2,3-C]-carbazoIe-5-13-quinones.
