Asymmetric synthesis of cyclopropanes from lithiated aryloxiranes and α,β-unsaturated fischer carbene complexes

A diastereo- and enantiospecific formation of tetrasubstituted cyclopropane carbene complexes and cyclopropanecarboxylates from lithiated aryloxiranes and α,β-unsaturated Fischer carbene complexes is described.

Furan-2(3H)- and -2(5H)-ones. Part 6. Di-?-methane rearrangement of the α-substituted 4-benzylfuran-2(5H)-one system

The effect of the 'central methane' substitution on the di-?-methane rearrangement in 4-benzyl-2,5-dihydrofuran-2-ones 8a-d was investigated.Significant enhancement of efficiency in the rearrangement leading in high combined yields to two isomeric products, endo-12 and exo-12, is discussed in terms of both the substituent effects at the benzylic carbon and the restrained features of the ring-enrolled ?-system.The origin of the difference in chemoselectivity compared with that of the 3-benzyl counterpart 5 where a photoarylated product 6 resulted upon photoirradiation was also investigated, and was rationalized by postulating a higher reactivity at the β-position of the enone system.

ACCENTUATION OF THE DI-?-METHANE REACTIVITY BY CENTRAL CARBON SUBSTITUTION IN THE 4-(PHENYLMETHYL)-2(5H)-FURANONE SYSTEM

The effect of 'central methane' substitution on the di-?-methane rearrangement in 4-(phenylmethyl)-2(5H)-furanones (1b-d) was investigated.Significant enhancement of efficiency in the reaction leading in high combined yields to two isomeric products (endo-2 and exo-2) was discussed in terms of both the substituent effects at the allylic methane carbon and the restrained feature of the ring-enrolled ?-system.

Reaction of HCo(CO)4 with Methyl 2,3-Diphenyl-2-cyclopropene-1-carboxylate: Synthesis of Methyl t,t-2,3-Diphenyl-c-2-formylcyclopropane-r-1-carboxylate

Reaction of HCo(CO)4 with the diphenylcyclopropene 1 leads to the three possible hydrogenated cyclopropanes but in addition a single hydroformylation product is formed.This aldehyde was synthesized by an unambiguous procedure; it is compound 2, formed by
