Abstract
The reaction of 3,4-di-t-butylthiophene 1-oxide (1) with 2-methylene-1,3-di methylimidazolidine (2) gave 4,4a-di(t-butyl)-1a,4a-dihydro-1H-cyclopropa[b ]thiophene and 1,3-dimethyl-2-imidazolidinone through a methylene transfer from 2 to 1, in addition to a [4+4] cyclodimerization product of 1.
