Nitromethyl benzoate annulation reactions: a rapid construction of the stealthin skeleton
摘要:
The annulation of 2-(nitromethyl)benzoates with enones gave 4-nitro-1-naphthols in good yields. The carbocyclic framework of the stealthins was synthesized. (C) 2012 Elsevier Ltd. All rights reserved.

and H(2)O, oxidation of phenol derivatives 1-10 afforded spiro 2-hydroxydienones in 24-55% yields regardless of the presence of other substituents (ortho Me, meta Me or Br) on the aryl ring and the length of the linker. Experimental evidences were provided to support the mechanism that involves a regioselective pi bond epoxidation of aryl rings followed by epoxide rearrangement and hemiketal formation

9-tetrahydro-7H-benzocyclohepten-7-ones 11 (Schemes 5 and 6), since the lead compound for the olfactory note of perfumes based on marine accords is a well-known benzodioxepinone named Calone 1951® (9b). We meticulously described the odor profile of each synthesized compound and discussed relevant structure–odor relationships (Tables 1–3). In particular, we revealed a correlation between the conformation of the seven-membered
