Benz isoquinolines synthesis

Benz[g]isoquinoline, l,4-ethano-l,2,3,4-tetrahydro-nomenclature, 1, 20 Benz[g]isoquinolinequinone synthesis... 

Increasingly, this process has been adapted to the synthesis of heterocyclic systems. One or both of the phenyl substituents in stilbene can be replaced by a heteroaromatic system, and some of the more important of these cyclizations are recorded in Table I. The formation of benz[A]isoquinoline by photolysis of 4-styrylpyridine in cyclohexane is accompanied by the formation of 1- and 3-cyclo-hexylbenz[A]isoquinoline.346... 

Cervinomycins (126 and 127) have captured interest as synthetic targets for organic synthesis. So far two approaches [104, 105] for the synthesis of partial structures and one total synthesis [106] of cervinomycin have been reported. At the outset, the rationale of the synthetic tactics towards these molecules was to secure an appropriate methodology for constructing the oxazolo-[3,2]-benz(o)isoquinoline skeleton. We envisioned that this moiety might be prepared in a single step from the corresponding isocoumarin (137) and ethanolamine.
