Reaction of lithiated 2-trimethylsilyl-1,3-dithiane with (±)-pantolactone
摘要:
Pantolactone methoxymethyl ether reacted with lithiated 2-trimethylsilyl-1,3-dithiane to give the corresponding ketene dithioacetal and formal monoaddition product of silicon-free 2-lithio-1,3-dithiane at a ratio of 2:1. Possible ways of formation of the latter are discussed.
