Convenient syntheses of 3-aryl-3,4-dihydroisocoumarins
A convenient method for the synthesis of naturally occurring 3,4-dihydroisocoumarins by judicious use of Friedel-Craft acylation, regioselective formylation and oxidative cyclisation reactions is described. O-methylated analogues of montroumarin and thunb

Reactions of the Carbanion from an Orsellinate Derivative with Electrophiles
Esters of orsellinic acid dimethyl ether (11) are attacked by alkyl-lithium reagents to give ketones and in some cases smaller amounts of alkenes as a result of a second nucleophilic attack.However at -78 deg C attack on (11) by its own anion (10) is suff
