Formal synthesis of linderone and lucidone based on one-pot cyclizations of 1,3-bis-silyl enol ethers with oxalyl chloride
A formal synthesis of the acylcyclopentenediones linderone and lucidone is reported which is based on the cyclization of 2,4-bis(trimethylsilyloxy)-1,3,5- hexatrienes with oxalyl chloride and on the synthesis and functionalization of γ-(2-silyloxypropenyl
