Organic Heterocyclothiazenes. Part 14. Aminotrithiadiazepines and Trithiadiazepyne
Plater, M. John,Rees, Charles W.
, p. 301 - 309 (2007/10/02)
Amino derivatives of the trithiadiazepine ring are described for the first time, as moderately stable crystalline solids.They are readily formed from the monobromo derivative by nucleophilic substitution under remarkably mild conditions, though only via t
Trithadiazepyne
Plater, M. John,Rees, Charles W.
, p. 1317 - 1319 (2007/10/02)
6,7-Didehydrotrithiadiazepine (trithiadiazepyne) (3) is readily generated from 6-bromotrithiadiazepine (1) with Huenig's base or sodium methoxide, and is intercepted in high yield by dienes and nucleophiles; formation of the highly stabilised carbanion (2
Aminotrithiadiazepines
Plater, M. John,Rees, Charles W.,Slawin, Alexandra M. Z.,Williams, David J.
, p. 1315 - 1317 (2007/10/02)
Amino derivatives 3 of the trithiadiazepine ring are moderately stable crystalline solids, readily prepared from 6-bromotrithiadiazepine 1 and ammonia or amines under remarkably mild conditions; unusually for aromatic amines, the amino groups are tetrahedral and are not conjugated with, but are orthogonal to, the 10 ? heteroaromatic rings, all of which form infinite overlapping stacks in the crystals.
TRITHIADIAZEPYNE
Plater, M. J.,Rees, C. W.
, p. 261 - 288 (2007/10/02)
Amino derivatives of the trithiadiazepine ring system are described for the first time.They are available by nucleophilic aromatic substitution under remarkably mild conditions, though only via the hetaryne intermediate.Firm evidence is presented for the involvement of this relatively stable aryne, and some new rearrangements accompanying or following its interception by dienes and dipoles are described.
