On the Lewis acid-catalysed reaction of the 2,3-bis(trimethylstannyl)-1-alkene moiety with aldehydes
摘要:
Compounds containing the 2,3-bis(trimethylstannyl)-1-alkene moiety react with aldehydes in the presence of boron trifluoride etherate to give homoallylic alcohols in which the remaining vinylic stannyl moiety has undergone halodemethylation. A mechanistic explanation for this behaviour is presented. NMR studies indicate that the addition proceeds in an erythro-selective manner.
