Abstract
The reductive opening of substituted phthalans 6, 11, 12, 20, 21 and 28 with lithium and a catalytic amount of DTBB leads to the formation of corresponding functionalised organolithium intermediates 8, 15, 16, 23, 25 and 29+ 30 in a regioselective manner. The further reaction of these dianions with different electrophiles, mainly carbonyl compounds, gives the expected functionalised benzylic alcohols 9, 17, 18, 24, 26 and 31+ 32. The ...
