Annulation of Eight- to Ten-Membered Oxaza Rings to the Benzo[b]thiophene System by Intramolecular Nucleophilic Displacement

Roger F. C. Brown Memorial Issue

“…[14] Joel Hooper, J. W. White, and Andrew Holmes (Melbourne) describe the use of a Claisen rearrangement with an organocatalytic, intramolecular Diels-Alder reaction in natural product synthesis, [15] Mary Garson et al (UQ) report the isolation of a new 3-alkylpiperidine from Indonesian waters, [16] and John Bremner and Z. Wu (Wollogong) detail annulation of eight-to ten-membered oxaza rings to benzo [b] thiophene. [17] Chris Moody (Nottingham, UK) reports the use of Rh-catalyzed carbene insertion in the synthesis of indoxylic acid esters. [18] Jonathan White, Ken Ghiggino and co-workers (Melbourne) elucidate solvatochromism in diketopyrrolopyrrole derivatives with the aid of calculations, [19] Jason Smith (UTas), Rolf Prager (Flinders) and co-workers report on the synthesis of heterocyclic fused imidazoles by FVP of isoxoazol-5(2H)ones, [20] and Ross McGeary (another former Roger Brown student) and his co-workers (UQ) use ethyl (benzothiazol-2ylsulfonyl)acetate in malonic ester-type syntheses of carboxylic acids and esters.…”
