Ishii, Keitaro published the artcilePhotoreactions of ¦Â-aziridinylacrylonitriles and acrylates with alkenes: the substituent effects on the formation of [3+2] cycloadducts, SDS of cas: 4141-48-4, the publication is Tetrahedron (2006), 62(47), 10865-10878, database is CAplus.
The photochem. C,C-bond cleavage of trisubstituted aziridines I (R1 = H, PhCH2; R2 = Me, Ph; R3 = H; R4 = CN, EtO2C) followed by [3 + 2] cycloaddition with electron-deficient alkenes, such as tert-Bu acrylate, afforded the novel head-to-head adducts, 1,2,3,5-tetrasubstituted pyrrolidines, e.g. II, selectively and efficiently. The aziridine (cis,Z)-I (R1 = PhCH2; R2 = Me; R3 = H; R4 = CN) reacted with mol. oxygen affording dioxazolidine III, whereas (trans,E)-I (R1 = PhCH2; R2 = Ph; R3 = H; R4 = EtO2C) produced only cleaved products. The results may suggest that the C,C-bond of aziridine cleaves biradically. The photoreactions of N-tritylaziridines I (R1 = Ph3C; R2 = H; R3 = R4 = MeO2C, CN; R3 = H, R4 = H2C:CH) possessing diester, dinitrile, and butadiene groups in the side chain with electron-deficient alkenes, such as vinyl acetate or acrylonitrile, yielded 2,3-cis-pyrrolidines IV exclusively. In particular, the dinitrile I (R1 = Ph3C; R2 = H; R3 = R4 = CN) also reacted with non-electron-deficient alkenes, such as isoprene. The formal synthesis of the indolizidine fragment of stellettamides starting from the pyrrolidine (E)-IV (R3 = H; R4 = H2C:CH; R5 = CN) was achieved in a convenient manner.
