Synthesis of dicyclopropanes from 4,7,7-Trimethyl-3-oxabicyclo[4.1.0]hept-4-en-2-one
摘要:
New optically active dicyclopropanes were synthesized on the basis of transformation products of 4,7,7-trimethyl-3-oxabicyclo[4.1.0]hept-4-en-2-one using dichlorocarbene or sulfoxonium ylide in the key cyclopropanation stages.
