Enantioselective synthesis of (1R,2S) and (1S,2S) dehydrocoronamic acids
Fliche,Braun,Le Goffic
, p. 2873 - 2876 (1994)
Thanks to the successive use of two esterases with different regioselectivities and conventional organic chemistry we have synthesized (1R,2S) and (1S,2S) dehydrocoronamic acids.
Advanced asymmetric synthesis of (1R,2S)-1-amino-2-vinylcyclopropanecarboxylic acid by alkylation/cyclization of newly designed axially chiral Ni(II) complex of glycine Schiff base
Kawashima, Aki,Shu, Shuangjie,Takeda, Ryosuke,Kawamura, Akie,Sato, Tatsunori,Moriwaki, Hiroki,Wang, Jiang,Izawa, Kunisuke,Acea, Jos Luis,Soloshonok, Vadim A.,Liu, Hong

Asymmetric synthesis of (1R,2S)-1-amino-2-vinylcyclopropanecarboxylic acid (vinyl-ACCA) is in extremely high demand due to the pharmaceutical importance of this tailor-made, sterically constrained α-amino acid. Here we report the development of an advanced procedure for preparation of the target amino acid via two-step SN2 and SN2′ alkylation of novel axially chiral nucleophilic glycine equivalent. Excellent yields and diastereoselectivity coupled with reliable and easy scalability render this method of immediate use for practical synthesis of (1R,2S)-vinyl-ACCA.

supporting information; experimental part, p. 277 - 280 (2011/03/20)
A trichloroisocyanuric acid (TCCA) mediated Hofmann rearrangement was utilized to synthesize methyl-1-(tert-butoxycarbonylamino)-2- vinylcyclopropanecarboxylate. A variety of functional groups are tolerated in this reaction including vinyl, cyclopropyl, pyridyl, aryl, benzyl, and nitro groups.
