Miscellaneous cyclizations

Miscellaneous Cyclizations of Carbonyl Derivatives to Form Benzothiophenes 906... [Pg.864]

A few other miscellaneous cyclizations are worthy of mention. o-Substituted benzene derivatives of general structure 382 (X = O, S or NH) undergo oxidative cyclization on irradiation to give the corresponding heterocyclic system (383),402 Similar behavior is exhibited by a thioamide [Eq. (102)]. Nonoxidative photoeyclization... [Pg.107]

Other miscellaneous cyclization reactions leading to interesting thiophene derivatives include a thermal conversion of a 2,2 -bis(A/,Af-dimethylthiocarbamoyloxy)-1,1 -binaphthyl into a dinaphtho[2,l-6 l, 2 -t/ thiophene (a heterohelicene) <0581109>, solution-phase parallel synthesis of a 1140-member ureidothiophene earboxylic acid hbrary <05JCC253>, and an unexpected cyclization occurring upon metalation of diphenylsulfone, followed by introduction of (-)-fenchone and subsequent aqueous workup <05T10449>. Heating of the... [Pg.130]
