6,7-Unsaturated carbonyl radicals, generated by the action of Bu3SnH on the corresponding selenol esters, cyclize to give either cyclohexanones or cycloheptanones, depending on the nature and position of the substituents in the hydrocarbon chain. Thus, cyclization of PhSeCOCH2CHRCH2CHR1CH:CH2 (I, R = H, R1 = OEt) with Bu3SnH gave 27% cycloheptanone II, while I (R = OSiPh2CMe3, R1 = H) gave 57% cyclohexanone III and 17% cycloheptanone II. In all cases, uncyclized aldehydes were isolated as byproducts. Allyloxy selenol esters cyclized similarly to give oxacyclohexanones and oxacyclaheptanones.
Tetrahedron Letters published new progress about Cyclization. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Category: esters-buliding-blocks.
