Aromatic substituent effect on the stereoselectivity of the condensed- and gas-phase acid-induced methanolysis in 2-aryloxiranes derived from 3,4-dihydronaphthalene and trans-1,2,3,4,4a,10a-hexahydrophenanthrene bearing a tertiary benzylic oxirane nucleophilic centre
摘要:
The ring-opening reactions with MeOH of the title benzocondensed 2-aryl oxiranes 6 and 7a,b both in the condensed (methanolysis) and in the gas phase were examined, obtaining in all cases a good Hammett-type linear correlation. Results indicate that the secondary or tertiary nature of the benzylic oxirane carbon is not responsible for the different stereochemical behavior so far encountered in different 2-aryl oxirane systems under the same operating conditions.

Tandem elimination-oxidation of tertiary benzylic alcohols with an oxoammonium salt

日期:——
alcohols react with oxoammonium salts, undergoing a tandem elimination/allylic oxidation to provide an allylicether product in a single step. This mode of reactivity provides a rapid entry into allylicethers from certain benzylic tertiary alcohols. The allylicether may be cleaved under reductive conditions to reveal the allylic alcohol.

with Na2CO3 is the key to substantially improving the reaction rate, substrate scope, and product stability in the KR of racemic tertiary alcohols using commercially available lipase A from Candida antarctica. The KR conditions were applied to cyclic tertiary alcohols containing tetralin, dihydroindene, chromane, and thiochromane moieties, yielding esters with excellent enantioselectivities.
