The TiCl4-mediated [3+3] cyclization of 4-alkyl- and 4-chloroalkyl-1,3-bis(trimethylsilyloxy)buta-1,3-dienes with 3-silylalk-2-en-1-ones afforded 3-alkyl- and 3-chloroalkyl-2-hydroxybenzoates, respectively; the latter containing a remote chlori
Synthesis of functionalized benzopyrans by sequential [3+3]-cyclization- Williamson reactions of 1,3-bis(trimethylsilyloxy)-7-chlorohepta-1,3-dienes

Functionalized benzopyrans were regioselectively prepared by [3+3]-cyclization of 1,3-bis(trimethylsilyloxy)-7-chlorohepta-1,3-dienes with 3-silyloxy-2-eno-1-ones and subsequent intramolecular Williamson reactions of the salicylates thus formed.
