Transformation of 1-(1,2-propadienyl)cyclopropanols into substituted hydroquinones employing octacarbonyldicobalt
摘要:
A novel transformation of 1-(1,2-propadieny])cyclopropanols into substituted 1,4-hydroquinones has been developed utilizing the interaction of 1.2-propadienes and octacarbonyldicobalt (Co-2(CO)(8)) This reaction was applied to the synthesis of vitamin E and K analogs. (C) 1997 Elsevier Science Ltd.

corresponding cyclopentenones has been undertaken with the aid of an alkyl substituent on the three-memberedring. These ring expansion reactions proceed with exceptional regioselectivity irrespective of the cis/trans stereochemistry of the substituents on the three-memberedring. β-Carbon elimination is the common feature in the absence of a chelating group at the 4′-position in the alkyne chain.
