Synthesis of 4H-3,1-benzoxazines by the reaction of o-(N-acylamino)benzyl alcohols with dast

The treatment of o-(N-acylamino)benzyl alcohols (1) with DAST afforded the dehydrative cyclization product, 4H-3,1-benzoxazines (4) and the hydroxy replacement product, o-(N-acylamino)benzyl fluorides (5). The yields of benzoxazines (4) and fluorides (5)

Sulfur-containing heterocycles derived by reaction of N-thioacylamino alcohols with Lawesson's reagent and saponification of N-thioacylamino esters

The treatment of 2-N-thioacylamino alcohols (1) with Lawesson's reagent [LR: 2,4-bis(p-methoxyphenyl)-1,3,2,4-dithiaphosphetane 2,4-disulfide] afforded the sulfur-containing heterocycles, 1,3-thiazolines (2) in moderate to good yields, exclusively. The sa

Heterocyclic 8?-Systems, 15. Investigations on Indole 2,3-Oxides: Sythesis of 3-Hydroxyindoles via Intramolecular Wittig-Rearrangement of 1,2-Dihydro-4H-3,1-benzoxazines

Investigations to trap indole 2,3-oxides 11 by base catalyzed ring contraction of 4H-3,1-benzoxazines 3 led in the system KNH2/NH3 to 3-hydroxy-3H-indoles 7.The N-methylbenzoxazinium salts 15, obtained from 3 and FSO3CH3, yielded with ethoxide under kinet
