Cyclobutanecarbonyl chloride

Cyclobutanecarbonyl chloride, reaction with erythro-2,3-butanediol monomesylate, 51, 12... [Pg.57]

Cyclobutanecarbonyl chloride was obtained from Aldrich Chemical Company, Inc. It was distilled prior to use. The acid chloride can be prepared by the reaction of thionyl chloride with the corresponding acid (available from Aldrich) by the general procedure of Helferich and Schaefer.3 The preparation of cyclobutanecarboxylic acid has been described in Organic. Syntheses4 and elsewhere.r>... [Pg.8]

CYCLOBUTANE, l-BROMO-3-CHLORO-, 51,106 Cyclobutanecarbonyl chloride, reaction with erythro- 2,3-butane-diol monomesylate, 51,12 CYCLOBUTANECARBOXALDE-HYDE, 51,11... [Pg.77]

A limitation of the ring expansion reaction is seen when a cyclobutanecarbonyl chloride is reacted. While treatment of D-nor-5a-androstane-16a-carbonyl chloride with 3-chloroperoxybenzoic acid gave the normal product D-nor-5a-androstan-16a-ol (9) via the acyl aroyl peroxide, the only isolated product from the epimer D-nor-5a-androstane-16/ -carbonyl chlo-... [Pg.375]

Using a somewhat similar reaction sequence cw-l-bromo-2-vinylcyclopropane was reacted with various acid chlorides and transformed stereospecifically to 1-acyl-2-vinylcyclopro-panes. Very good yields were obtained thus, when the bromide was allowed to react successively with tert-butyllithium, phenylsulfanylcopper and cyclobutanecarbonyl chloride at — 78 °C, cyclobutyl d5-2-vinylcyclopropyl ketone (2a) was isolated in 93% yield. [Pg.1342]
