Synthesis of 8,8′-Disubstituted 1,1′-Binaphthyls Stable to Atropisomerization: 2,2′-Dimethyl-1,1′-binaphthalene-8,8′-diol and 2,2′-Dimethyl-8,8′-bis(4-tert-butyloxazolyl)-1,1′-binaphthyl

Axially chiral binaphthyls 3a and 3b were synthesized taking, advantage of Ullman coupling of 4a and 4b, respectively. The binaphthyls were shown to be stable to atropisomerization. Binaphthol 3b was resolved with (-)-(1S)-menthyl chloroformate (11). R-axis diastereomer of bisoxazoline 3b was used for enantioselective cyclopropanation of styrene with ethyl diazoacetate.

An easily accessible route to the 1,7-dicarbaldehyde 7-monodimethylacetal 7 is described.It proceeds in a six step sequence from the known 7-methyl-1-tetralone.

A series of naphthalenyl 3H-1,2,3,5-oxathiadiazole 2-oxides was prepared and tested for antihyperglycemic activity in the db/db mouse, a model for type 2 (non-insulin dependent) diabetes mellitus.Substitution at the 1-,5-, or 8-positions of the naphthalene ring with a halogen was found to be beneficial to antihyperglycemic activity. 4--3H-1,2,3,5-oxathiadiazole 2-oxide (45), one of the most potent compounds in this series, was selected for further pharmacological evaluation.
