Diphenylprolinol silyl ether I (R1 = H, R2 = H, TMS, TBS; R1 = CF3, R2 = TMS) was found to catalyze the formal carbo [3 + 3] cycloaddition reaction through the domino reaction via the Michael reaction, followed by Knoevenagel condensation of the α,β-unsaturated aldehyde and di-Me 3-oxopentanedioate, affording substituted cyclohexenone derivatives, e.g. II, with excellent enantioselectivity.
Organic Letters published new progress about Cycloaddition reaction (asym. formal [3+3]). 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Application of C9H7BrO.
