A novel approach to chiral, nonracemic pyrrolidines by 5-exo-trig diastereoselective radical cyclization on acrylamides derived from (-)-8- aminomenthol

α,β-Unsaturated amides supported on perhydro-1,3-benzoxazines derived from (-)-8-aminomenthol as chiral auxiliaries undergo regio- and stereoselective 5-exo-trig radical cyclization leading to diastereomeric five-membered lactams. These cyclization products are transformed into enantiopure 3,4-disubstituted pyrrolidines by reduction with aluminum hydride followed by removal of the menthol appendage.

Preparation of Silyl Enol Ethers Derived from α-Phenylseleno aldehydes and α-Phenylseleno ketones

The best experimental conditions for the preparation of trimethylsilyl enol ethers 3 from α-phenylseleno aldehydes 1, compatible with a limited deselenenylation of the substrate, were studied.Starting from α-phenylseleno ketones 2, the enoxysilanes 4, bearing a vinylic PhSe group, are the major products when triethylamine is the base.Trimethylsilyl enol ethers 5 with an allylic PhSe group are also formed beside 4 when LDA or KH are used at lower temperatures.

Preparations de composes α-arylselenocarbonyles a l'aide de morpholinoareneselenenamides

The reactivity of the morpholinoareneselenenamides 1 which are readily prepared from various diaryldiselenides, is investigated.The selenenamides 1 are good α-selenenylating agents for aliphatic aldehydes, α-ketoesters and conjugated enals yielding the α-

α-PHENYLSELENENYLATION D'ALDEHYDES - SYNTHESE SIMPLE D'α-CETOALDEHYDES A FONCTION CETONE PROTEGEE

Morpholinophenylselenenamide 2 add to β-phenylselenoenamines 1a and yield β,β-bis(phenylseleno) enamines 4.These compound undergo hydrolysis to form bis(phenylseleno) ethanal 5a.Also, 2 react with enolic aldehydes to give α-phenylselenoaldehydes 3.This re
