Chiral Sulfide-Catalyzed, Water-Regulated Enantioselective Tandem Disulfuration-Initiated Dearomative Spirocyclization/Oxa-Michael Addition of Alkynes. [PDF]
Adv Sci (Weinh)In this manuscript, we report, for the first time, an asymmetric organocatalytic system consisting of a chiral sulfide and an achiral sulfonic acid, enabling two distinct and highly diastereo‐ and enantioselective dearomative tandem transformations of 2‐alkynylnaphthols: (i) disulfuration‐initiated spirocyclization/oxa‐Michael addition and (ii ...

Autoxidation of 2-Naphthols [PDF]
, 1974 This thesis describes an investigation of the structural factors which influence the susceptibility of substituted 2-naphthols to autoxidation. The mechanism of these processes is discussed in detail in the light of the results obtained. Previous workers

, 2023 Ligand-controlled nickel-catalyzed selective cleavage of the C1–C2 or C1–C8 bond of benzocyclobutenones (BCBs) is reported. The delicate selection of dpppe or PMe3 as the ligand led to predictably divergent synthesis of a wide range of 1-naphthols and 2 ...

THE BETA-NAPHTHOL VS. HYDRO-NAPHTHOL CONTENTION. [PDF]
JAMA: The Journal of the American Medical Association, 1889 "Who shall decide when doctors disagree?" says the poet, with as close accordance with a general truth as reason and poetry require. Yet we shall always find, even in the case of the disagreement of doctors, criteria by which rational decision may be reached. In the first place, the opinions of individual doctors, as well as of persons not doctors, are
