SnCl2/AgOTf

Heterocycliz/oHon. Indoles are obtained when anilines and trialkanolamines are treated with RuClj, PhjP, and SnCl2-2H20 in dioxane," and dihydrobenzofurans from 2-allylphenols with RuClj hydrate, AgOTf, Cu(OTf)j, and PhjP. It appears that 2-(3-butenyl)phenol also undergoes cyclization to give benzopyran derivatives. [Pg.324]

The authors showed that treatment of mannosyl donor 8 with DDQ and alcohols a-c gave the mixed acetals 9a-9c (Scheme 4). Without purification, 9a-9c were activated with AgOTf and SnCl2 in the presence of DBMP. Aqueous work-up gave the expected P-mannopyranosides 10a 10c in good overall yields. [Pg.452]
