15357621-2	2004	Intramolecular 1,3-dipolar nitrone cycloaddition reaction of d-glucose-derived precursors having olefin at C-3 and nitrone at C-5, C-1, or C-2 (in nor-series) furnished bisisoxazolidinospirocycles 4-7, 11, and 12 in good yields.	Alkenes	97-103	complement C3	Homo sapiens	107-110	
11667407-2	1996	The olefin undergoes two types of palladium-catalyzed reactions: (a) arylation to provide C-3 arylated derivatives and (b) competing double bond isomerization.	Alkenes	4-10	complement C3	Homo sapiens	90-93	
14519449-6	2003	Substitution of the alkyne moiety between C-3 and C-4 by an alkene (B and E) or alkane (D) blocked completely the anti-adhesive effect.	Alkenes	60-66	complement C3	Homo sapiens	42-45	
29577133-1	2018	An efficient strategy for the synthesis of C-2 and C-3 branched sugar dienes via cross dehydrogenative coupling of sugar enol ethers with terminal alkenes was developed.	Alkenes	147-154	complement C3	Homo sapiens	51-54	
26863099-2	2016	The developed protocol introduces pentafulvenes as nonsymmetrical alkenes for the hydroheteroarylation reaction, providing alkylidenecyclopentenylation at the C-3 position of indoles and the C-2 position of pyrrole.	Alkenes	66-73	complement C3	Homo sapiens	159-162	
24823713-4	2014	Moreover, a robust strategy for the introduction of the exo-methylene group at C-3, commonly found in many sesquiterpenes, was developed that makes use of masking the alkene in the alpha,beta-unsaturated carbonyl system by O-pivaoyl, which is stable under acidic and mild basic conditions but eliminated upon treatment with strong bases.	Alkenes	167-173	complement C3	Homo sapiens	79-82
