Asymmetric intramolecular C–H insertion of sulfonyldiazoacetates catalyzed by Rh(II)
摘要:
The asymmetric C-H insertion of alkyldiazosulfones has been studied. High selectivity was achieved using a combination of a chiral catalyst and a chiral auxiliary (Rh-2(S-pttl)(4) and menthyl ester). Published by Elsevier Ltd.

The synthesis of new optically active alkanediylbis- and alkanetriyltris(diphenylphosphines) is described. Easily accessible optically pure lactones and carboxylic acids are reduced to the alcohols, tosylated and reacted with lithium diphenylphosphide to give the corresponding phosphines.
