The answer is in thermodynamics and kinetics.In a document type is Article, 2081-44-9, the author is Fernandez-Salas, Jose A. and a compound is mentioned, 2081-44-9, Tetrahydro-2H-pyran-4-ol, introducing its new discovery.

Intermolecular alkyl radical additions to enantiopure N-tert-butanesulfinyl aldimines

The sulfinyl group in (R)-N-tert-butanesulfinyl aldimines provides efficient control of the stereoselectivity in the intermolecular reactions with alkyl radicals. The methodology is applicable to aryl, heteroaryl, benzyl, and alkynyl imines, even those containing CN, CO2Me, COR, and OH groups. The best results are attained with hindered radicals (tertiary and secondary ones) without C=N bond reduction. This reaction complements the well-established organometallic additions to N-sulfinyl aldimines to obtain enantiomerically pure functionalized alpha-branched primary amines.

2081-44-9, Tetrahydro-2H-pyran-4-ol is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a solution of tetrahydropyran-4-ol (15.0 g, 146 mmol, 14.71 mL) in dichloromethane (600 mL) was added PPh3 (50.0 g, 191 mmol) and imidazole (15.0 g, 220 mmol). The mixture was stirred at 0 C and iodine (44.7 g, 176 mmol) was added in portions under a nitrogen atmosphere. Finally, the mixture was stirred at 15 C for 16 hours. On completion, the reaction mixture was filtered and the filtrate was concentrated in vacuo to get a residue. The residue was diluted with water (150 mL) and extracted with ethyl acetate (3 ¡Á 150 mL). The combined organic layers were dried over anhydrous Na2SO4, filtered and concentrated in vacuo to give a residue. The residue was purified by column chromatography (petroleum ether: dichloromethane = 1:0 to 2:1) to give the title compound (16.0 g, 51% yield) as a colorless oil.1H NMR (400MHz, CDCl3) delta = 4.48 – 4.41 (m, 1H), 3.80 (td, J = 4.4, 11.6 Hz, 2H), 3.56 – 3.46 (m, 2H), 2.20 – 2.09 (m, 4H).
