To demonstrate the synthetic utility of the developed organocascade reaction, we performed a reaction between 1a and 2a in gram scale, giving the product 3a in 61% yield with retained stereochemical outcomes (99% ee, and dr >20/1, Scheme 4A). To reduce reaction time, the reaction was performed with a slightly higher amount of C1 (3 mol%). As an example of late-stage transformations, spirooxindole 3a was selectively converted to various derivatives (Scheme 4B). N-Boc protecting group was removed by treatment of 3a with an excess of TFA. Rection provided the corresponding spirooxindole 3f in excellent yield with retained enantioselectivity. Noteworthy, the sequence of the developed organocascade followed by N-deprotection is more appropriate compared to the direct organocascade reaction starting from 1f. Next, DBU-mediated elimination of HNO2 produced alkene 5a in excellent yield with retained optical purity. Noteworthy, the double bond of alkene 5a can be selectively reduced under catalytic hydrogenation conditions, producing cyclopentane derivative 9 with high diastereocontrol. The relative configuration of 9 was determined by 1D NOE NMR experiments (for more information, please, see the SI). Furthermore, ethyl ester 5a can be chemoselectively reduced to corresponding allylic alcohol 9 by treatment with DIBALH. Spirocyclic allylic alcohol 10 may be used as a valuable building block for synthesizing valuable complex molecules. 18 Scheme 4. Gram-scale organocascade reaction and latestage transformations.
