General procedure for the synthesis of compounds 3, 5, 7, 9 General procedure: To a solution of 1 or 4 or 6 or 8 (0.12 mmol) and 2 (0.10 mmol) in H2O (1 mL) was added Cs2CO3 (32.5 mg, 0.10 mmol) and CTAB(2.0 mg, 5 mol%). The mixture was further stirred at room temperature for the indicated time. Once starting material was consumed (monitored by TLC), the mixture was filtered and the residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate 8:1 to 3:1) to afford the corresponding product.

Yield	Reaction Conditions	Operation in experiment
84%	With cetyltrimethylammonim bromide; caesium carbonate In water at 20℃; for 24h;	4.2. General procedure for the synthesis of compounds 3, 5, 7, 9 General procedure: To a solution of 1 or 4 or 6 or 8 (0.12 mmol) and 2 (0.10 mmol) in H2O (1 mL) was added Cs2CO3 (32.5 mg, 0.10 mmol) and CTAB(2.0 mg, 5 mol%). The mixture was further stirred at room temperature for the indicated time. Once starting material was consumed (monitored by TLC), the mixture was filtered and the residue was purified by column chromatography on silica gel (petroleum ether/ethyl acetate 8:1 to 3:1) to afford the corresponding product.

Yield	Reaction Conditions	Operation in experiment
53%	With sodium tetrahydroborate; oxygen; potassium carbonate In N,N-dimethyl-formamide at 50℃; Molecular sieve;	One-Pot Oxidative Decyanation of Alkylidenemalononitriles to Alcohols; General Procedures A-1 and A-2 General procedure: The corresponding alkylidenemalononitrile (procedure A-1) or alkylmalononitrile (procedure A-2) substrate (1 equiv.) was dissolved in DMF (0.1 M) in a flame-dried Schlenk flask under positive pressure N2 along with 3 Å molecular sieves (~20 mg/mL of solvent). Using an O2 balloon, O2 gas was gently bubbled though the reaction mixture using a long needle through the reaction flask septum. O2 was bubbled for 10 min. After 10 min, NaBH4 (4 equiv. for alkylidenemalononitriles and 2 equiv. for alkylmalononitriles) was then added and the reaction mixture was stirred for 2-5 min (until effervescence stopped). Then, K2CO3 (2 equiv.) was added and the reaction mixture was heated at 50 °C. O2 was bubbled through the mixture until reaction completion. Once completion was achieved (monitored by TLC), the reaction mixture was cooled to rt and the O2 balloon was removed. The excess NaBH4 was slowly quenched with H2O (1 mL) and the reaction mixture was diluted with 2 M HCl(aq) (5 times the reaction volume). The resulting aqueous mixture was extracted with EtOAc three times (2 times the aqueous phase volume). The combined organic layers were washed with 2 M HCl(aq) (equal volume as the organic phase) and brine (equal volume as the organic phase), and dried over Na2SO4. The EtOAc was removed under reduced pressure and the crude was purified via silica gel column chromatography (Hex/EtOAc).
