cze	Syntesa hexahelicenu a 1-Methoxyhexahelicenu cestou cycloisomerizace biphenylyl-naphthalenových derivátů	Nový přístup nonphotochemické syntézy z heliceneů je založený na snadném a modulárním shromáždění klíčových biphenylyl- naftalenů za katalýzy platinou cycloizomerizací. Tato sekvence reakcí poskytuje cestu k syntéze helicenů ve dvou krocích z snadno přístupných elementů. Vyvinutá strategie je doložená syntézou z 6,10 - dimethylhexahelicenu a 1 - methoxy -6,10-dimethylhexahelicenu	hexaheliceny;1-methoxyhexaheliceny
eng	Synthesis of Hexahelicene and 1-Methoxyhexahelicene via Cycloisomerization of Biphenylyl-Naphthalene Derivatives	The new approach provides nonphotochemical syntheses of helicenes based on the easy, convergent, and modular assembly of key biphenylyl-naphthalenes and their platinum-catalyzed double cycloisomerization. This sequence of reactions provides a synthetic route to helicenes in two steps from simply accessible building blocks. Furthermore, the method enables the introduction of substituents into the hexahelicene skeleton. The strategy developed is exemplified by the synthesis of 6,10-dimethylhexahelicene and 1-methoxy-6,10-dimethylhexahelicene.	Hexahelicene;1-Methoxyhexahelicene
